【摘要】 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。更多还原
【Abstract】 The γ rays following the β+/EC decay of 176,178Ir nuclei have been investigated using in-beamγ-ray experiment.A total of 4 new levels,13 new γ transitions of 176Os and 5 new levels,14 new γ transitions of 178Os were identified.In addition,with the aid of a helium-jet recoil fast tape transport system,the(β+/EC) decay of 176Ir was further studied,the above new γ rays were proved and an isomer was proposed in 176Ir.By the semiempirical calculations of two-quasiparticle intrinsic states of odd-odd nuclei,the configurations of ground states and isomeric states were also proposed for 176,178Ir.更多还原
