Abstract
Excited states have been observed for the first time in the neutron deficie nt nuclei Os-166 and Os-164. The nuclei were produced using the reactions C d-106(Cu-63,p2n) Os-166, Sn-112(Ni-58,2p,2n) Os-166, and Cd-106(Ni-60,2n)Os -164 at beam energies of 292, 286, and 257 MeV, respectively. The gamma ray s emitted by Os-166 and Os-164 were identified by correlating the associate d recoil evaporation residues with their subsequent characteristic a decays . The deduced level schemes indicate that Os-166 and Os-164 continue the tr end of decreasing deformation moving away from the N = 104 midshell. The le vel energy systematics of the low-spin states are presented.
