Coulomb Excitation of <sup>74</sup>Ge

ORAL

Abstract

The electromagnetic properties of low-lying states in 74Ge have been investigated using a multi-step coulomb excitation measurement carried out at the ATLAS facility of the Argonne National Laboratory. The experimental setup consisted of the GRETINA multidetector array coupled to the heavy-ion counter, CHICO2. This coupling allowed for precise Doppler correction and clean kinematic separation of the scattered particles. The ground-state and quasi-gamma bands were coulomb excited to spins 8+ and 4+, respectively. Preliminary results from the analysis will be presented in the context of similar studies performed for the neighboring 72,76Ge [1, 2] nuclei.
