The level structure of Se83 was studied via prompt γ-ray spectroscopy of fragments following the fission of the compound nucleus Th226 formed in the O18 (91 MeV) + Pb208 fusion-evaporation reaction. The first four high-spin states above the 9/2+ ground state were established. The coupling of the neutron hole in the g9/2 orbital to the yrast states in the Se84 core can account for these states. The experimentally observed high-spin states are compared with predictions of shell-model calculations.
