Abstract

The investigation of the excitation energies of the 2₁ ⁺ -states in the neutron-rich Cd isotopes shows an irregular behaviour when approaching the neutron shell-closure at N = 82. The energy of the 2₁⁺-state in ¹²⁸Cd is lower than the one in ¹²⁶Cd. The transition strength B(E2, 0_gs⁺ → 2₁⁺) in the even isotopes ^122-128Cd was measured in Coulomb excitation experiments with the high-purity germanium detector array MINIBALL at REXISOLDE (CERN). The values for ^122,124Cd coincide with beyond-mean-field calculations with a resultant prolate deformation, whereas ^126,128Cd are better described by shell-model calculations.
