High-spin states in the odd-odd Re have been investigated via the Sm(Al,4n)Re reaction through excitation functions, x-γand γ-γcoincidence measurements. A level scheme consisting of three rotational bands have been identified for the first time extending the high-spin studies of A～160 odd-odd nuclei to the currently lightest rhenium isotope. The three bands have

High-spin states in 169Re have been investigated by means of in-beam 7-ray spectroscopy techniques with the 144Sm(28Si, 1p2n) 169Re reaction. X-γ and γ-γ-t coincidences, 7-ray anisotropies, and DCO ratios were measured. A strongly coupled band based on the 9/2-[514] Nilsson state and a decoupled band built on the h9/2 intruder proton orbital (nominally 1/2- [541]) have been established. The AB neutron crossings are observed at hω=0.23 and 0.27 meV for the 9/2-[514] and 1/2-[541] bands, respectively. The difference between the

High-spin states in 179Au have been studied experimentally by using the 149Sm(35Cl, 5n) reaction at beam energies of 164-180 meV. The 35C1 beam was provided by the tandem accelerator at the Japan Atomic Energy Research Institute (JAERI). The target is an isotopically enriched 149Sm metallic foil of 1.5 mg/cm2 thickness with a 5.0 mg/cm2 Pb backing. measurements of γ-ray excitation functions, X-γ coincidences and γ-γ-t coincidences were performed with 13 HPGe's with BGO anti-Compton shields and three LOAX detectors.
