Abstract
Excited states in the neutron-deficient isotopes Os and Os were identified using the JUROGAM and GREAT spectrometers in conjunction with the RITU gas-filled separator. The Os and Os nuclei were populated via the Cd(Ni,3) and Mo(Kr,23) reactions at bombarding energies of 270 MeV and 357 MeV, respectively. Gamma-ray emissions from these nuclei have been established unambiguously using the recoil-decay tagging technique and a coincidence analysis has allowed level schemes to be established. These results suggest that the yrast states are based upon negative-parity configurations originating from the and orbitals.
