The level structure of ^(190)Pt has been studied experimentally using the ^(176)Yb(^(18)O,4n)reaction at beam energies of 88 and 95 MeV.γ-γ-t coincidence measurements were carried out.Based on the analysis ofγ-γcoincidence relationships,the level scheme of ^(190)pt is extended to high-spin states.A new structure built on the 3413.6 keV 14^+ state has been observed,and the vi_(13/2)^(-2) vh_(9/2)^(-1) vj(j=P_(3/2) or f_(5/2))configuration is tentatively assigned to it.
