Abstract
We report on the “safe” Coulomb excitation of neutron-rich Cd, Xe, and Ba isotopes in the vicinity of the doubly magic nucleus 132Sn. The radioactive nuclei have been produced by ISOLDE at CERN and postaccelerated by the REX-ISOLDE facility. The g-decay of excited states has been detected by the MINIBALL array. Preliminary results for the B(E2) values are consistent with expectations from phenomenological systematics and are compared with theoretical calculations.
