The first experiment using radioactive beams post-accelerated by the HIE-ISOLDE facility has enabled to obtain a precise set of B(E2) transition probabilities in neutron-rich 74,76Zn isotopes. The resulting B(E2; 2+1 -> 0+1 ) values are consistent with those determined in earlier REX-ISOLDE measurements. While the B(E2; 4+1 -> 2+1 ) transition probability in 76Zn is also in agreement with earlier Coulomb-excitation results, the value obtained for 74Zn is considerably lower. For the first time, a spectroscopic quadrupole moment of the 2+1 state was measured for an exotic nucleus in this mass region. A detailed comparison is presented with large-scale shell-model and Monte Carlo shell-model calculations.
The low-energy electromagnetic structure of Cd-110 was studied using safe-energy Coulomb excitation at the Heavy Ion Laboratory, University of Warsaw. The preliminary results on the quadrupole deformation of low-lying 0(+) states in Cd-110 are presented and compared to the recent beyond-mean-field and General Bohr Hamiltonian calculations.
