A Coulomb-excitation measurement to study low-energy electromagnetic properties of 45Sc has been performed at the IUAC facility in New Delhi, India using a 70 MeV 32S projectile from the 15UD tandem accelerator. The preliminary value of the reduced transition probability B(E2, 11/2- ! 7/2-) and the resulting lifetime for the 11/2- state at 1237 keV were determined using the GOSIA code.

In order to gain further information on the electromagnetic properties of the low-lying states in 45Sc, a Coulomb excitation measurement was carried out at the IUAC, New Delhi. The 45Sc target nuclei were Coulomb excited by the 70 MeV 32S beam from the 15UD tandem accelerator. The -rays depopulating Coulomb excited states in 45Sc were detected by four Clover detectors in coincidence with the forward scattered ions. The main aim of the experiment was to determine the B(E3; 7=2- → 3=2+) and B(E3; 7=2- → 5=2+) transition probabilities, as well as the transitional electromagnetic matrix elements for low-lying intruder states.

The last stable tellurium nucleus on the neutron-deficient side, 120Te, was Coulomb excited using two different projectiles. The low-lying collective states were populated in a multi-step Coulomb excitation process. Magnitudes and relative signs of the reduced E2 matrix elements were determined using the GOSIA code. The resulting set of E2 matrix elements was analysed using the quadrupole sum rules approach to determine the quadrupole deformation parameters for the 0+1 and 2+1states. [ABSTRACT FROM AUTHOR]

A new accelerator facility -- Cyclotron Centre Bronowice (CCB) -- was opened two years ago in Kraków, Poland. Aside from cancer therapy, a scientific program of the nuclear structure research making use of proton beams in the energy range of 70-230 MeV plays a significant role as well. Lead and graphite targets were used to prove the feasibility of exclusive experiments on collective modes in various nuclei. The experimental technique consists of simultaneous energy measurement of scattered beam particles in coincidence with γ rays emitted from excited nuclei. This article describes the set-up and the method of analysis used for the experiment. [ABSTRACT FROM AUTHOR]

Low-lying excited states of 104Pd were investigated by means of Coulomb excitation using the 32S beam. Gamma-ray spectra resulting from the deexcitation of these levels were measured with the EAGLE gamma-ray spectrometer at the Heavy Ion Laboratory, University ofWarsaw. The first three excited states above the ground state up to 6+ level were populated alongwith the low-lying non-yrast states. Excitation of the 3- state at 2194 keV energy was also observed.

Lifetimes of high-spin states in As have been measured using Doppler shift attenuation technique with the GASP and RFD set-up. The nucleus of interest was populated in the 40Ca(32S, 3p) 69As reaction at beam energy of 95 MeV. Extracted lifetimes for the 33/2+ state at 7897 keV and 37/2+ state at 9820 keV are 72 (-45, +55) fs and 25(-25, +50) fs, respectively. The transition quadrupole moment resulting from the measurement can serve as a test of the TRS calculations. [ABSTRACT FROM AUTHOR]

Lifetimes of high-spin states in 66Ge have been measured using Doppler shift attenuation technique with the GASP and RFD setup. The 66Ge nucleus was populated in the 40Ca(32S, α2p) reaction at beam energy of 95 MeV. The transition quadrupole moment, Qt, of the negative parity band in this nucleus has been determined to be approx. 0.9γ 0.1 eb. [ABSTRACT FROM AUTHOR]

We report on preliminary results from the experiment performed at Legnaro National Laboratories aiming at the investigation of the shape evolution of the 88Mo nucleus. The GDR spectra obtained for two data sets measured at 48Ti beam energy of 300 and 450 MeV corresponding to 3 and 3.8 MeV temperatures, respectively, are presented. The low energy component in GDR strength functions, similar to the theoretical predictions of LSD model, possibly indicates the presence of Jacobi shape transition. [ABSTRACT FROM AUTHOR]

The yrast structure of the neutron-rich nucleus 97Zr has been studied using fission of target-like products in the reaction of a 48Ca beam on a thick 238U target. The level scheme known from the previous studies up to an energy and spin of approx. 4619 keV and 23/2-, respectively, has been extended by about 3 MeV and a few units of angular momentum. The located structure can be discussed in terms of shell model configurations. [ABSTRACT FROM AUTHOR]

An experiment aiming at measuring lifetimes of the second 2+ excited states in neutron-rich C and O isotopes was recently performed at the GANIL laboratory, in France. In these nuclei, recent ab initio calculations provide a detailed description of the nuclear excited states, predicting a strong sensitivity of the electromagnetic transition probabilities to the details of the nucleon-nucleon interactions, especially in connection with the role played by the three-body (NNN) forces. Thus, the measurement of 2+ states lifetimes in this region will be a stringent test of the importance of including the NNN forces in describing the electromagnetic properties of selected nuclear states. This contribution reports on the status of the experimental analysis for the case of lifetimes in 20O. [ABSTRACT FROM AUTHOR]
