We report the results of an experiment in which we studied the near-yrast states in selenium isotopes approaching N = 50 following their population in multinucleon transfer reactions between a 82Se beam and a 192Os target. The level schemes for 80,82Se derived from the current work are compared with restricted-basis shell-model calculations and pair-truncated shell-model calculations. These provide a good description of the yrast sequences in these nuclei using a basis space limited to excitations in the (p3/2 , p1/2 , g9/2 ) and (f5/2 , p3/2 , p1/2 ) orbitals.

Keywords: nuclear Structure; gamma-ray spectroscopy; deep-inelastic reactions; shell model
