Abstract：
The level structure of 190Pt has been studied experimentally using the 176Yb (18O, 4n) reaction at beam energies of 88 and 95MeV. γ-γ-t coincidence measurements were carried out. Based on the analysis of γ-γ coincidence relationships, the level scheme of 190Pt has been extended to high-spin states. A new structure built on the 3413.6keV 14+ state has been observed, and the pi13/2(-2) *nh9/2(-1)nj (j=p3/2 or f5/2) configuration has been tentatively assigned to it.
