New Isotope ^265Bh was produced in bombardment of a ^243Am target with 168 MeV 26Mg ions. The experiment was carried out at the Sector Focus Cyclotron of Heavy Ion Research Facility in Lanzhou in 2003. The reaction products were transported and collected by using helium-jet technique and a set of rotating wheel system. Identification was made by observation of correlated a-particles between the new isotope ^265Bh and its ^261Db and ^257Lr daughter nuclei. A parent-daughter searching mode was used to facilitate detection of α-α correlations. A total of four pairs of PIPS detector (200mm^2 active area) were used to measure the kinetic energy of a particles. The a particle energy resolution was about 40 keV for the top detectors and 100 keV for the bottom detectors because of energy degradation in the polypropylene foil.

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

High-spin states in ^179Au have been studied experimentally by using the ^149Sm(^35C1, 5n) reaction at beam energies of 164,~180 MeV. The ^35C1 beam was provided by the tandem accelerator at the Japan Atomic En-ergy Research Institute (JAERI). The target is an isotopically enriched ^149Sm metallic foil of 1.5 mg/cm^2 thickness with a 5.0 mg/cm^2 Pb backing.
