Excited states in 196Os and the structure of the PtOs transition region

Abstract The 198 Pt( 14 C, 16 O) 196 Os reaction has been used to obtain the first evidence for excited states in 196 Os, in groups at excitation energies of 300 and 760 keV. The implications of these results for the structural evolution of the OsPt transition region are discussed. In addition, the first direct determination of the 196 Os ground-state mass is reported.
