The level structure of ^19Opt has been studied experimentally using the ^176yb （^18O, 4n） reaction at beam energies of 88 and 95 meV. γ-γ-t coincidence measurements were carried out. Based on the analysis of T-T coincidence relationships, the level scheme of ^190Pt is extended to high-spin states. A new structure built on the 3413.6 keV 14＋ state has been observed, and the ＂vi13/2^-2 vh9/2^-1 vj （j = P3/2 or f5/2） configuration is tentatively assigned to it.

High spin states in 80Rb were studied via the 65Cu+19F, 66Zn+18O and 68Zn+16O reactions. The 75-meV 19F, 76-meV 18O and 80-meV 16O beams were provided by the CIAE HI-13 Tandem accelerator and the JAERI Tandem accelerator. The prompt γ-γ coincidence and the directional correlation from oriented nuclei (DCO) were measured by the detector arrays in CIAE and JAERI. Twenty-three new states with 28 new transitions have been assigned to 80Rb. The states were observed up to spins of 20+ and 22− in the α = 0 branch for the positive and negative parity yrast bands respectively. The negative parity non-yrast bands were significantly extended up to spins of 22− and 15−. The band crossings with frequencies 0.51meV and 0.61meV in the α = 0 cascade were observed for the first time. The signature splitting was observed in both negative parity bands. The signature inversions at spins of about 7 and 15 were observed.
