Low-spin electromagnetic transition probabilities in 102,104Cd

Lifetimes of low-lying states in Cd-102,Cd-104 were determined by using the recoil distance Doppler-shift technique with a plunger device and a Ge array consisting of five HP Ge detectors and one Euroball cluster detector. The experiments were carried out at the Cologne FN Tandem facility using the Mo-92(C-12,2n)Cd-102 reaction at 41 MeV and the Mo-94(C-12,2n)Cd-104 reaction at 42 MeV. The differential decay curve method in coincidence mode was employed to derive the lifetime of the first 2(+) state in both nuclei and the lifetime of the 4(+) state in Cd-104. The corresponding reduced E2 transition probabilities have been studied within the framework of the nuclear shell model.
