利用在束实验产生具有β+/EC衰变性质核素176,178Ir,分析了在束实验条件下获得的γ-γ符合数据,识别出了176Os的4条新能级和13条新γ跃迁、178Os的5条新能级和14条新γ跃迁。籍助氦喷嘴快速带传输系统,进一步对176Ir的β+/EC衰变进行了测量,在确认在束测量新γ射线的同时建议了176Ir的一个低自旋同核异能态。通过两准粒子耦合的半经验计算,建议了176,178Ir基态及同核异能态的组态。

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. 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.

We established the level scheme of 145Tb for the first time. The excited states below 2 meV have been interpreted qualitatively by coupling an h11/2 valence proton to the 0+, 2+, 4+ and 3- excited states in the 144Gd core nucleus, and the yrast levels in excitation energy range from 2.1 to 3.4 meV have been suggested from the (πh211/2d-15/2/g-17/2) proton excitations or the couplings of the h11/2 proton to the 5- and 7- yrast

The level structure of doubly odd nucleus 146Tb has been studied via the 118Sn(32S, 1p 3n)146Tb reaction by using techniques of in-beam γ-iay spectroscopy. measurements of 7-ray excitation functions, 7-ray anisotropies, X-γ and γ-γ-t coincidences were performed with 12 BGO(AC)HPGe detectors. Based on the γ-γ coincidence relationships, intensity balances and cross-over transitions, the level scheme of 146Tb has been extended up to
