Abstract

The investigation of the excitation energies of the 2(1)(+)-states in the neutron-rich Cd isotopes shows an irregular behaviour when approaching the neutron shell-closure at N = 82. The energy of the 2(1)(+)-state in Cd-128 is lower than the one in Cd-126. The transition strength B(E2, 0(gs)(+) -> 2(1)(+)) in the even isotopes Cd122-128 was measured in Coulomb excitation experiments with the high-purity germanium detector array MINIBALL at REX-ISOLDE (CERN). The values for Cd-122,Cd-124 coincide with beyond-mean-field calculations with a resultant prolate deformation, whereas Cd-126,Cd-128 are better described by shell-model calculations.
