Abstract

High spin states of175, 176Pt have been populated in144Sm(35Cl,pxn) reactions at beam energies of 175–185 MeV. In-beamγ-ray spectroscopic techniques using the ESSA30 spectrometer array were adopted. Levels up to spin 26 in176Pt and tentatively up to spin 45/2 in175Pt have been identified. The data are interpreted within the framework of Cranked Shell Model calculations using the deformed Woods-Saxon potential and including monopole pairing.
