Excited states in 124Xe have been studied via the 12C(124Xe,124Xe*) Coulomb excitation reaction. Relative cross‐sections have been determined from the γ‐ray yields observed with Gammasphere. The E2 strengths between the low‐spin states in 124Xe have been determined. The results clearly show the realization of the O(5) symmetry even for the off‐yrast states with high τ, while the O(6) symmetry seems to be already broken.

Understanding the nuclear structure of 152Sm, along with other N = 90 isotones, has long posed a challenge. A rapid transition in shape between the spherical N = 88 150Sm and well‐deformed N = 92 154Sm is observed, along with strong evidence for shape coexistence. Competing ideas have been put forward over the decades, with the most recent being that N = 90 is at the critical point of a shape phase transition. Until recently, the lack of high‐precision data has not allowed the competing models to be extensively tested. In a coordinated program of investigation, a series of complementary experiments, which include high‐statistics β decay, multi‐step Coulomb excitation, the 150Nd(α,2n) reaction, and the (n,n′γ) reaction, have been performed for 152Sm. These experiments have revealed the existence of a pairing‐isomer band, a hexadecapole band, the lack of multi‐phonon β vibrational bands, and the repetition of structures built on the first excited Kπ = 0+ as built on the ground state. The status of these coo...

It has been shown that the (3He,t) charge exchange reaction at intermediate energies, used at zero momentum transfer in combination with high‐resolution magnetic spectrometers is a very powerful probe for Gamow‐Teller strengths. Several N = Z nuclei such as 46V [1] or 50Mn [2] have been investigated. Recently ab‐initio nuclear structure calculations have become possible for light nuclei. Thus experimental studies on light nuclei have become of great current interest [3]. We review previous results obtained in 11C with respect to nuclear structure aspects and the Hoyle state, and present some early results of a 9Be(3He,t)9B experiment carried out recently, pointing out the significance of high‐resolution charge‐exchange reactions and the investigation of Gamow‐Teller strengths for the understanding of nuclear structure in light nuclei.

We report on systematic investigations of low‐lying electric dipole (E1) strength in atomic nuclei. Using the method of real photon scattering the dipole response of all stable N = 82 isotones has been measured with high resolution. In all cases a resonance like structure of E1 strength is observed in the energy region 5–8 MeV, which shows a strong fragmentation. The total integrated strength increases towards the proton poorer isotones, indicating a dependence of the total strength on the neutron‐to‐proton ratio. The experimental results are compared to microscopic calculations within the Quasi‐particle Phonon Model (QPM). By including complex configurations of up to three phonons the calculation is able to reproduce also the fragmentation of the E1 strength and is in good agreement with the experimental observation.

Low‐lying collective states in 136Ba were investigated with (n,n′γ) techniques, including Doppler‐shift attenuation lifetime measurements. The level spins, lifetimes, branching ratios, multipole‐mixing ratios and transition strengths reveal candidates for symmetric‐phonon states up to third order. The 2ms+ mixed‐symmetry state was confirmed as unfragmented and a candidate for a [21+⊗2ms+]3+ two‐phonon mixed‐symmetry state is proposed.

The rate of the 17F(p,γ)18Ne reaction is of significant importance in astrophysical events like novae and x‐ray bursts. A 3+ state in 18Ne predicted to dominate the rate was found at 599.8 keV using the 17F(p,p)17F reaction [1], but the resonance strength was unknown. For the first time, the 17F(p,γ)18Ne reaction has been measured directly with the Daresbury Recoil Separator, using a mixed beam of radioactive 17F and stable 17O from the HRIBF at ORNL. A γ width was found for the 599.8 keV resonance in 18Ne, and an upper limit on the direct capture S factor was determined at an intermediate energy of 800 keV.

Resonances in the 12C(16O,γ)28Si radiative capture process at energies around the Coulomb barrier have been probed using the very selective 0° Dragon spectrometer at Triumf and its associated BGO γ‐array. For the first time the full level scheme involved in this process has been measured and shows previously unobserved γ‐decay to doorway states around 11 MeV in 28Si.

Thermal neutron capture gamma-ray spectra for {sup 187}Re(n,{gamma}){sup 188}Re reaction were measured. Singles and coincidence spectra were detected in order to develop the level scheme. The evaluation is in progress, of which the first results are obtained from the analysis of coincidence spectra, allowing to check the level scheme below 500 keV excitation energy. Seven low-energy negative parity bands are developed in order to find better energies for rotational levels. With a good confidence, a few positive parity bands are developed as well. Rotor plus two quasiparticle model calculations, employing effective matrix element method are performed for the system of six negative parity rotational bands.

High quality radioactive beams have recently made possible the measurement of (d,p) reactions on unstable nuclei in inverse kinematics, which can yield information on the development of single-neutron structure away from stability, and are of astrophysical interest due to the proximity to suggested r-process paths. The Oak Ridge Rutgers University Barrel Array (ORRUBA) is a new high solid-angular coverage array, composed of two rings of silicon detectors, optimized for measuring (d,p) reactions. A partial implementation has been used to measure (d,p) reactions on nuclei around the N = 82 shell closure.

Existing experimental data on γ decay of energy levels in medium‐weight and heavy nuclei at excitation energies well above the pairing gap indicate that the role of nuclear structure effects is small and that this decay is largely governed by the extreme statistical model. Specifically, in line with the validity of Brink hypothesis and the paradigm of photon strength, the average properties of the γ decay can be described by a set of photon strength functions (PSFs) for individual multipolarities and by the level density function. PSFs are directly related to the photoabsorption cross sections σγ abs. It is well known that in the case of E1 radiation this cross section is dominated by the giant dipole electric resonance. However the size of σγ abs. and its γ‐ray energy dependence at energies below the neutron threshold are known rather poorly. In the case of higher multipolarities (M1, E2,…) the present knowledge about their roles is much worse. Available information on E1 and M1 PSFs obtained from variou...

By using an empirical power law function with two fit parameters, the multiplet splitting for more than 30 pure particle‐hole states (with values between −0.3 and +0.6 MeV) is described with a residual energy difference of about 0.03 MeV.

A search for an anomalous n‐p scattering from a polyethylene sample (CH2) at 8 final energies between 64 eV and 2.5 keV was carried out. The scattering intensities were compared to that from a graphite (C) sample. The results were found to confirm our previous n‐p results on H2O at a final energy of 24.3 keV where no n‐p scattering anomaly was observed. The present results refute all proposed models attempting to explain the occurrence of any n‐p scattering anomaly at keV neutron energies.

The advantages of using inelastic neutron scattering with detection of the emitted γ rays, i.e., the (n,n′γ) reaction, for exploring the structure of stable nuclei are reviewed. Examples of the information available with these techniques are provided and progress in understanding multiphonon excitations is described. The unique nuclear structure of 94Zr is discussed.

Positron‐electron pair creation near the threshold energy is extremely difficult to investigate by both experiments and theory. First test experiments were performed at the ILL to determine the cross sections for positron‐electron pair creation near threshold using prompt γ‐rays from different targets after neutron capture and conventional radioactive sources. Pair creation was studied in a Ge detector, which simultaneously acted as sample and detector. First results are presented which show a significant deviation from theoretical values near threshold.

Multipole mixing ratios for transitions between excited 2+ states and the 21+ state in 140Nd are measured using angular correlation techniques for beta decay reactions. Two transitions with dominant M1 components are identified, and the higher‐lying 2+ states involved in these transitions are presented as candidates for the one‐phonon mixed‐symmetric 2+ state in 140Nd. Assuming pure two‐state mixing between the one‐phonon 2+ state and a presumed three‐phonon symmetric state yields a mixing matrix element between these states, which is discussed in terms of shell effects on mixed‐symmetric behavior in the N = 80 isotones.

Lifetimes and g‐factors have been measured for short‐lived low‐lying states in 70Zn using the techniques of projectile Coulomb excitation in inverse kinematics combined with transient magnetic fields and the Doppler‐Shift‐Attenuation‐Method (DSAM). While the g(21+) value was redetermined and found to be consistent with the literature values, all other data are new. The main goal is a better understanding of the influence of the v(g9/2) orbital in this region of the nuclear chart.

We study the structure of isomeric state 21+ in the odd‐odd N = Z nucleus 94Ag using a shell model, which is capable of describing the spectra of upper g9/2‐shell nuclei close to the N = Z line. It is shown that the 21+ state becomes isomeric because of level inversion of the 19+ and 21+ states due to core excitations across the N = Z = 50 shell gap. Calculation of spectroscopic quadrupole moment indicates clearly an enhancement in these states due to the core excitations. In the present shell model calculation, however, the large‐deformation picture of Mukha et al. in Nature 439, 298 (2006) cannot be accepted.

Using the HORUS spectrometer at the Cologne FN‐TANDEM accelerator, we performed a γγ coincidence measurement on 88Zr. The reaction used was 89Y(p,2n)88Zr. A particular point of interest was the search for a potential 2+ mixed‐symmetric state. In the experiment, we measured the multipole mixing ratios of the decays of the 22+ and the 23+ states and determined the energies of the 23+ and 02+ states precisely. Furthermore, we found two new levels and seven new γ transitions.

Energies and electromagnetic transitions in 16O are evaluated by an equation of motion method which generates iteratively a microscopic multiphonon basis and solves exactly the nuclear eigenvalue problem in such a basis. The computed quantities are greatly affected by the multiphonon configurations and by the center of mass motion, here completely removed.

Using the Advanced Time‐Delayed method we have studied transition rates in several neutron‐rich nuclei at the magic shell closures. These include the heavy Co and Fe nuclei just below the Z = 28 shell closure at the point of transition from spherical to collective structures. Of particular interest is 63Fe located exactly at the point of transition at N = 37. A substantial increase in the information on this nucleus was obtained from a brief fast timing study conducted at ISOLDE. The new results indicate that 63Fe seems to depart from a simple shell model structure observed for heavier N = 37 isotones of 65Ni and 67Zn.Another region of interest are the heavy Cd and Sn nuclei at N = 72, 74 and the properties of negative parity quasi‐particle excitations. These experiments, performed at the IGISOL separator at Jyvaskyla, revealed interesting properties of the E2 rates in the sequence of E2 transitions connecting the 10+, 8+, 6+, 4+, 2+ and 0+ members of the multiplet of levels in 122Sn due to neutrons in th...

An essential property of collectivity is the proton‐neutron degree of freedom, that leads to the so‐called states of mixed symmetry. Predictions for the electromagnetic decay of the lowest‐lying mixed‐symmetry state 2MS,1+ in vibrator‐like even‐A nuclei are a strong M1 decay to the fully‐symmetric 21+ state and a weak collective E2 decay to the ground state 01+. Excited states in 62Zn have been studied via the 61Ni(3He,2nγ) reaction using the HORUS‐cube spectrometer of the Institute for Nuclear Physics in Cologne. Two fragments of the mixed‐symmetry state 2MS,1+ could be identified by determining absolute M1 transition strengths to the 21+ state.

The lifetimes of excited states of the 122Ba ground—state band, populated via the 108Cd(16O,2n)122Ba and the 112Sn(13C,2n)122Ba reactions, have been measured using the Recoil Distance Doppler—Shift method. The level scheme of 122Ba has also been revised.

The N = 52 nucleus 98Pd was investigated at the Cologne TANDEM accelerator both with the Cologne plunger using the recoil distance Doppler‐shift method (RDDS) and with the Cologne HORUS spectrometer for a γγ angular correlation experiment. For the first time lifetimes of yrast states and highly excited low‐spin states were measured in 98Pd and the low‐spin level scheme was extended. From our data we were able to interpret 98Pd as a nucleus that exhibits some collective features, but is obviously much less collective than the neighboring N = 52 isotones 94Mo and 96Ru due to its closeness to doubly‐magic 100Sn.

Electromagnetic dipole absorption cross‐sections of transitional nuclei with large‐amplitude shape fluctuations are calculated in a microscopic way by introducing the concept of instantaneous‐shape sampling. The concept bases on the slow shape dynamics as compared to the dipole vibrations. The dipole strength is calculated by means of RPA for the instantaneous shapes, the probability of which is obtained by means of IBA‐1. Very good agreement with the experimental absorption cross sections near the nucleon emission threshold is obtained.

Recently, an Orange spectrometer, a focusing iron‐free magnetic spectrometer, has been installed at a beam line of the 10 MV Tandem accelerator of the IKP of the University of Cologne. The high efficiency of 15% of 4π for the detection of conversion electrons and the energy resolution of 1% makes the Orange spectrometer a powerful instrument. From the conversion electron spectrum, transition multipolarities can be determined using the so called K to L ratio. In combination with an array of germanium and lanthanum bromide detectors, e−‐γ‐coincidences can be performed to investigate the level scheme. Moreover, the very fast lanthanum bromide scintillator with an energy resolution of 3% allows e−‐γ lifetime measurements down to 0.3 ns. A second Orange spectrometer can be added to build the Double Orange Spectrometer for e−‐e−‐coincidences. It is indispensable for lifetime measurements of low intensity or nearby lying transitions as often occur in odd‐A and odd‐odd nuclei. The capabilities are illustrated wit...

High‐resolution inelastic electron scattering experiments were performed at the S‐DALINAC for a precise determination of the partial pair width Γπ of the second Jπ = 0+ state, the so‐called Hoyle state, in 12C. Results for the monopole matrix element (directly related to Γπ) from a nearly model‐independent analysis based on an extrapolation of low‐q data to zero momentum transfer are presented. Additionally, a Fourier‐Bessel analysis of the transition form factor is discussed. The combined result of both methods leads to a pair width Γπ62.2(10) μeV.

With the nearly monochromatic, linearly polarized photon beam at the High Intensity γ‐ray source (HIγS) at DFELL photon scattering experiments on 206,207,208pb have been performed. With these experiments Pb(γ,γ′) photon scattering reactions could be used to determine spin and parity quantum numbers and therefore study the v(3p1/2−1‐hole coupling of 207Pb to dipole excitations in 208Pb

It is shown that the Mallmann’s energy correlations, introduced a long time ago for the ground state bands of the even‐even nuclei are, in fact, universal. Various bands in all collective nuclei (even‐even, odd‐even, and odd‐odd) obey the same systematics. This unique, universal behaviour indicates the same spin dependence of the energy of the levels and, consequently, a common structure of all collective bands. Based on the second‐order anharmonic vibrator description, parameter‐free recurrence relations between energy ratios are deduced. These relations can be used to predict levels of higher spins in various bands.

Spectra of the 9Be(e,e′) reaction have been measured at the S‐DALINAC at an electron energy E0 = 73 MeV and scattering angles of 93° and 141° with high energy resolution up to excitation energies Ex = 8 MeV. The astrophysically relevant 9Be(γ,n) cross sections have been extracted from the (e,e′) data. The resonance parameters of the first 1/2+ state in 9Be have been derived in a one‐level R‐matrix approximation resulting in a resonance energy ER = 1.748(6) MeV and a resonance width ΓR = 274(8) keV These parameters are in mutual agreement with those obtained from the latest real photon experiments but with improved uncertainties.

The nuclear structure of neutron‐rich N⩾126 nuclei have been investigated following their production via relativistic projectile fragmentation of a E/A = 1 GeV 238U beam on a Be target. The cocktail of secondary beam products were separated and identified using the GSI FRagment Separator (FRS). The nuclei of interest were implanted in a high‐granularity active stopper detector set‐up consisting of 6 double sided silicon strip detectors. The associated gamma‐ray transitions were detected with the RISING array, consisting of 15 Euroball cluster Ge‐detectors. Time‐correlated gamma decays from individually identified nuclear species have been recorded, allowing the clean identification of isomeric decays.

The Zr isotopes between 90Zr and 96Zr are expected to be spherical based on the almost complete subshell closures at Z = 40 and N = 50, 56. On the other hand, they have low‐lying 3− states and show the characteristics of low frequency octupole oscillation which arise as a superposition of particle‐hole excitations. A 380 MeV 94Zr beam from the tandem accelerator at the Japan Atomic Energy Agency (JAEA) was excited on a self‐supporting natPb target. The gamma‐ray detector array GEMINI‐II was used to detect deexcitation gamma rays. The scattered beam (94Zr) was detected with a position‐sensitive particle detector system. The gamma‐ray intensities were used as an input to the least‐squares search code GOSIA to determine the E3 matrix element of the first 3− excited state of 94Zr. The B(E3;0+→3−) value of 0.21(6) e2b3 in 94Zr has been obtained by Coulomb excitation experiment.

Particle‐triaxial rotor calculations have been performed for the negative parity states in 195Pt and 193Os. The doublet structure of the low‐lying excited states is better described when a Woods‐Saxon potential is used compared to the use of a modified harmonic oscillator potential. The predicted level energies and B(E2) transition strengths are in overall agreement with the experimental data and the U(6/12) results. The ratios of B(E2) values between the states of two doublets agree well with those obtained assuming a pseudospin symmetry. In 193Os, the model calculations can be used for clarification of the spin assignments in cases where they are ambiguous. It is interesting to check them by new precise spin determination.

Coulomb excitation experiments in inverse kinematics on beams of stable {sup 134,132,130,128,126,124}Xe ions impinging on a carbon target at energies of 82% of the respective Coulomb barriers have been performed. The one-phonon 2{sub 1,ms}{sup +} states have been tracked and identified in {sup 134,132,130,128}Xe from the 2{sub i,ms}{sup +}{yields}2{sub 1}{sup +} M1 strength distributions and from 0{sub 1}{sup +}{yields}2{sub i,ms}{sup +} E2 strength distributions responsible for the one-step Coulomb excitation processes. The evolution of the one-phonon 2{sub 1,ms}{sup +} state within the seven even-even stable Xe isotopes is here presented.

In recent years collectivity in the mass region around A = 100 has become the focus of increased interest. The N = 52 isotones were investigated in detail and phonon excitations ‐especially one‐ and two‐phonon mixed‐symmetry states—were identified. In order to investigate how vibrator‐like behavior and states with mixed‐symmetry character evolve with increasing neutron number it is interesting to study the N = 54 isotones. Therefore an experiment to measure the low‐spin excitations of 100Pd was performed at the FN‐Tandem accelerator with the HORUS cube spectrometer. Besides the determination of excitation and transition energies and branching ratios, spins and multipole mixing ratios resulted from the γγ angular correlation analysis. The newly gained data were compared with predictions from theory both from collective models and from shell model.

The 72Ge(n,α)69mZn, 74Ge(n,α)71mZn, 76Ge(n,2n)75g+mGe reaction cross sections have been measured from 9.6 to 11.4 MeV and studied, along with data from literature, within the frame of the statistical model using the code EMPIRE‐II.

The comparisons of different phenomenological methods for calculation of vibrational and rotational enhancement factors of nuclear level density in spherical and deformed nuclei are performed. A practical method for the calculation of vibrational enhancement factor and level density parameters is recommended. The asymptotic level density parameters and additional energy shifts are obtained for 291 atomic nuclei. The systematics of these parameters are given.

In thin film technology, analytical methods for monitoring the deposition of oxide and nitride coatings and the effects of corrosive, laser and ion‐beam treatments have attracted considerable attention. For depth‐profiling the concentrations of light isotopes, resonant nuclear reaction analysis is an excellent non‐destructive ion‐beam analytical tool. We report here on precision measurements of the 278 keV 14N(p,γ) and the 151 keV 18O(p,α) resonances using the high‐resolution proton beam of the Gottingen IONAS accelerator. The deduced resonance energies ER and total widths Γ (in the laboratory system) are ER = 277.60(27) keV and Γ = 1115(33) eV for the 14N(p,γ) resonance, and ER = 150.97(26) keV and Γ = 178(35) eV for the 18O(p,α) resonance. These values are significantly more precise than the ones quoted in the literature.

Expérience KVI-Groningen; International audience; The beta-decay branching ratio of the GT transition in 21Na to the first excited state in 21Ne has been measured. The value obtained of 4.93(20)% is in agreement with the most recent measurement and with the value adopted so far. This confirms that the branching ratio is not the source of discrepancy in a previous measurement of beta−v correlation coefficient which exhibited a 3sigma difference with respect to the Standard Model prediction.

Two‐neutron separation energies, quadrupole moments and mean square charge radii, are evaluated for even‐even Osmium isotopes with 78⩽N⩽114. The calculations are performed in the framework of a microscopic model including the pairing correlations rigorously by means of the FSBCS (Fixed‐Sharp‐BCS) method.

The recently measured low‐energy spectra of the N = 80 isotones 134Xe, 136Ba and 138Ce have been investigated in the quasiparticle‐phonon model. The energies and transition strengths are well reproduced. While the observed selection rules reflect the neutron‐proton symmetry and phonon content of the excited states involved in the transitions, the splitting of the M1 strength in 138Ce is shown to be linked to a subtle interplay between pairing and single particle levels across the proton subshell closure.

Neutron transfer (d,p) reaction studies on the N = 50 isotones, 82Ge and 84Se, and A≈130 nuclei, 130,132Sn and 134Te, have been measured. Direct neutron capture cross sections for 82Ge and 84Se (n,γ) have been calculated and are combined with Hauser‐Feshbach expectations to estimate total (n,γ) cross sections. The A≈130 studies used an early implementation of the ORRUBA array of position‐sensitive silicon strip detectors for reaction proton measurements. Preliminary excitation energy and angular distribution results from the A≈130 measurements are reported.

To measure the form factor of isospin polarized one‐quadrupole phonon states of 92Zr at the Z = 40 proton subshell closure and to compare it to the momentum‐transfer dependence of the form factors for the one‐quadrupole phonon states predicted by the Quasiparticle Phonon Model, the 2+ states of 92Zr have been investigated with an electron scattering experiment at the S—DALINAC. The relative E2 excitation strength to off‐yrast 22+ state was also extracted in a model‐independent systematic procedure. A comparison with the data on 94Mo and previous spectroscopic information on MSSs of 92Zr will be given.To measure the form factor of isospin polarized one‐quadrupole phonon states of 92Zr at the Z = 40 proton subshell closure and to compare it to the momentum‐transfer dependence of the form factors for the one‐quadrupole phonon states predicted by the Quasiparticle Phonon Model, the 2+ states of 92Zr have been investigated with an electron scattering experiment at the S—DALINAC.

The spin cut‐off parameter σ has been determined for experimental low‐excitation energy spin distributions of 310 nuclei between 18F and 251Cf (more than 8000 levels with their spin). The results indicate a weak dependence on the mass number, σ2∼A0.30, and a strong even‐odd spin staggering in the even‐even nuclei.

Rational relations in values of stable intervals in near‐magic nuclei with Z = 26–29 confirm the presence of tuning effect in nuclear data.

The cross sections of 113In(α,γ)117Sb and 113In(α,n)116Sb reactions have been measured using the activation method. The experiments were carried out at the ATOMKI cyclotron accelerator in the center of mass energy range from 8.7 to 13.7 MeV. Astrophysical S‐factors have been calculated, and preliminary results are compared with statistical model predictions.

This paper presents a summary of the latest results from experiments performed at the Oslo Cyclotron. The Oslo group has developed a technique to extract simultaneously the level density and radiative strength function from primary γ‐ray spectra. A small (pygmy) resonance in the radiative strength function has been observed at around 3 MeV in several deformed rare earth nuclei. This resonance is shown to be of M1 character and the origin is thought to be the scissors mode. This resonance vanishes for the spherical Sm nuclei, as expected, since the scissors mode is dependent on deformation. Experiments performed in Oslo found the resonance in Dy isotopes to be twice as wide as the width extracted in an indirect way by comparing simulations with two‐step cascade spectra from neutron capture experiments. In 116,117Sn an increase in the slope of the radiative strength function around Eγ = 4.5 MeV indicates the onset of resonance‐like structures in both nuclei, resulting in a significant enhancement of the rad...

High‐sensitivity studies of E1 and M1 excitations observed in the 138Ba(γ,γ′) reaction at energies below the neutron emission threshold have been performed. The electric dipole character of the so‐called “pygmy” mode was experimentally verified for excitations from 4.0–8.6 MeV. The fine structure of the M1 “spin‐flip” mode was observed for the first time in N = 82 nuclei.

The study of (γ,n) reactions can be used to constrain the theoretical predictions of the neutron capture cross sections of short‐lived branching points in the s process. The usability of the activation technique to study these (γ,n) reactions is discussed as one example of an activation experiment in nuclear astrophysics. Two photon sources using bremsstrahlung and laser‐Compton backscattered photons where such experiments were carried out are compared.

Absolute transition probabilities of the first 2+ state in 110,114Pd were remeasured using the recoil distance Doppler shift technique following projectile Coulomb excitation at intermediate beam energies for the first time. The 110Pd experiment served to check the novel technique as well as the method used for the data analysis which is based on the examination of γ‐ray lineshapes. Whereas the measured B(E2) value for 110Pd agrees very well with the literature, the value obtained for 114Pd differs considerably. The data is also used to test a novel concept, called the valence proton symmetry, which allows one to extrapolate nuclear properties to very neutron rich nuclei.
