γ-ray spectroscopy of proton neutron-hole nucleus 208Bi from deep inelastic heavy ion reactions

γ rays in the πν-1 nucleus 208Bi have been studied at the Gammasphere using deep-inelastic reactions induced by a 305-MeV 48Ca beam on a thick 208Pb target. Previously unknown yrast γ-ray cascades above the 10- millisecond isomer in 208Bi were identified in cross coincidence with known γ rays from complementary potassium products. Yrast and near-yrast levels up to 5.6 MeV in 208Bi have been located, and they are interpreted in light of earlier charged particle spectroscopy results, and with the help of shell model calculations.
