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 = 0cascade were observed for the first time.The signature splitting was observed in both negative parity bands.The signature inversions at spins of about 7 h and 15 h were observed.
