Abstract
In the present contribution, the experimental investigation of the pos- sible occurrence of the shape coexistence phenomenon in the 83Se (Z = 34, N = 49) and 84Se (Z = 34, N = 50) isotopes is presented. The aim of the experiment was to identify excited states which may be associated with dif- ferent deformed shapes, i.e., spherical, oblate, and prolate. The structure of both nuclei was studied by using γ-ray spectroscopy techniques, and the states and transitions of interest were investigated in detail through lifetime measurements and angular correlations.
