High-spin states of Pt have been reinvestigated using the Yb(O, 4) reaction at a beam energy of 88 MeV. The previously known positive parity band associated with the ( being or ) configuration has been revised and extended significantly. A new negative parity band has been established and proposed to be based on the configuration. Possible structure evolution of the yrast line from predominantly vibrational to rotational with increasing spin is discussed with the help of E over spin curves. Additionally, calculations of Total Routhian surfaces have been performed to investigate the band properties.
