Abstract

International audience; The electromagnetic structure of Zn66 at low excitation energy was investigated via low-energy Coulomb excitation at INFN Legnaro National Laboratories, using the Gamma Array of Legnaro Infn Laboratories for nuclEar spectrOscopy (GALILEO) γ-ray spectrometer coupled to the SPIDER (Silicon PIe DEtectoR). A set of reduced E2, E3, and M1 matrix elements was extracted from the collected data using the gosia code, yielding 12 reduced transition probabilities between the low-spin states and the spectroscopic quadrupole moment of the 21+ state. The B(E2) values for transitions depopulating the 02+ state have been determined for the first time, allowing for the lifetime of this state to be deduced and, consequently, the ρ2(E0;02+→01+) monopole transition strength to be extracted. In addition, the B(E3;31−→01+) value has been determined for the first time in a Coulomb excitation experiment. The obtained results resolve the existing discrepancies between literature lifetimes and demonstrate that Zn66 cannot be described by using simple collective models. Therefore, new state-of-the-art beyond-mean-field and large-scale shell-model calculations were performed in order to interpret the structure of this nucleus. Both the experimental and theoretical results suggest that the triaxial degree of freedom has an important impact on electromagnetic properties of Zn66, while the unique features of the 02+ state indicate its distinct and rather isolated structure.

Abstract

Spectroscopic data, such as precise γ-ray branching and E2/M1 multipole-mixing ratios, provide vital constraints when performing multi-dimensional Coulomb-excitation analyses. Consequently, as part of our new Coulomb-excitation campaign aimed at investigating the role of exotic non-axial (triaxial) deformations in the unstable refractory Ru-Mo isotopes, additional beta-decay data was obtained. These measurements make use of ANL's CARIBU facility, which provides intense beams of radioactive refractory isotopes along with the excellent efficiency and angular resolution of the GRETINA γ-ray tracking array. In this article, we report on the analysis of the A = 110 decay chain, focussing on the identification of previously unreported states in 110Ru following the decay of 110Tc.

Abstract

The Radiopharmaceuticals Production and Research Centre was recently installed on the premises of the Heavy Ion Laboratory, University of Warsaw. Equipped with a medical PETtrace p/d cyclotron , radiochemistry synthesis and dispensing units and a modern quality control laboratory the Centre is intended to produce regularly for commercial purposes the classic PET radiopharmaceuticals ( such -as e.g. FDG- ). Situated on the largest Warsaw scientific campus OCHOTA, an important part of the Centre’s activities will also be devoted to the production of known species for preclinical studies and research into innovative radiopharmaceuticals in collaboration with other scientific units of this Campus as well as with members of the Warsaw Consortium for PET Collaboration. Research into the accelerator production route of 99mTc will also begin shortly.

Abstract

International audience; Background: The γ softness of Nd136 makes it possible to study the shape changes induced by two-proton or two-neutron excitation. Purpose: We measure the lifetimes of two-quasiparticle states of the bands based on the 10+ states at 3296 and 3279 keV to investigate the shape change induced by the alignment of two protons or two neutrons in the h11/2 orbital. Methods: The recoil-distance Doppler shift method was used for the study of Nd136 studies, which was formed by the fusion reaction Sn120(Ne20,4n)Nd136, at Ebeam=85 MeV. Calculations were performed within the microscopic-macroscopic approach, based on the deformed Woods-Saxon single-particle potential and the Yukawa-plus-exponential macroscopic energy. Results: The lifetime of the 10+ state at 3279 keV of Nd136 was measured to be T1/210+=1.63(9) ns. The lifetimes of the 2+ state at 374 keV and of the 12+ state at 3686 keV of the ground band were also measured to be T1/22+=26.5(14) ps and T1/212+=22.5(14) ps. Conclusions: The measured lifetime of 10+ the state at 3279 keV together with other observables confirm the structure change in Nd136. A rather small reduced hindrance of the electromagnetic decay of the 10+ state at 3279 keV would be consistent with its K-mixed character.

Abstract

International audience; In the region around 132Sn, the structure of even-even nuclei demonstrates diverse phenomenon including the transition between some typical quadrupole collective states. The doubly magic isotopic chain of Sn-isotopes seems to be the most interesting mass-region to be studied. Several theoretical and experimental studies have been focused in this mass region, recently [1]. The low-lying spectroscopy of these nuclei is one of the most powerful sources of information about nuclear shapes and shape transitions. Experimental/adopted B(E2↑) values for this mass-region are depicted in Fig. 1.

Abstract

Coulomb-excitation experiments to study electromagnetic properties of radioactive even-even Hg isotopes were performed with 2.85 MeV/nucleon mercury beams from REX-ISOLDE. Magnitudes and relative signs of the reduced E2 matrix elements that couple the ground state and low-lying excited states in 182−188Hg were extracted. Information on the deformation of the ground and the first excited 0+ states was deduced using the quadrupole sum rules approach. Results show that the ground state is slightly deformed and of oblate nature, while a larger deformation for the excited 0+ state was noted in 182,184Hg. The results are compared to beyond mean field and interacting-boson based models and interpreted within a two-state mixing model. Partial agreement with the model calculations was obtained. The presence of two different structures in the light even-mass mercury isotopes that coexist at low excitation energy is firmly established., The authors would like to thank the ISOLDE facility for providing excellent beams.

Abstract

Expérience GANIL; International audience; The weakening of the N = 28 shell closure and the development of deformation and shape coexistence were addressed in a low-energy Coulomb excitation experiment using a radioactive 44Ar beam from SPIRAL. The 2+ 1 and one higher-lying state in 44Ar were excited on 208Pb and 109Ag targets at two different beam energies. From the collected data it will be possible to extract the B(E2) values between all observed states and to determine the quadrupole moment of the first 2+ state, providing information on the prolate or oblate character of the deformation.

Author

Abstract

The E1 transition from the 3/2− state to the ground state of 229Pa was identified in the (p,tγ) reaction. Its energy is found to be 11.6(3) keV. This leads to a value of Qg.s.=−4133(2) keV and to a mass defect of 229Pa of 29894(3) keV. It is concluded that the ground-state configuration of 229Pa is 3/2[651]. [ABSTRACT FROM AUTHOR]
