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 ν(p3/2,p1/2,g9/2) and π(f5/2,p3/2,p1/2) orbitals.

Abstract
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 ν(p3/2,p1/2,g9/2) and π(f5/2,p3/2,p1/2) orbitals.
