^(183)Au核高自旋态转动带结构研究

Experimental Study of High-Spin Band Structures of ^(183)Au

通过重离子熔合蒸发反应和在束核谱学实验方法研究了奇A核183Au的高自旋态能级结构.扩展并更新了183Au的能级纲图.首次建立了183Au的πi13/2转动带的能量非优先带.分析并讨论了183Au中πh9/2转动带的能量非优先带和πf7/2转动带间的相互作用.

High-spin states in ^183Au have been studied experimentally using heavy-ion-induced fusion-evaporation reaction and standard in-beam γ-ray spectroscopic techniques. The level scheme of ^183Au was revised and extended. A rotational band proposed as the unfavored signature branch of the πi13/2 band has been observed for the first time. Interaction properties between the two negative-signature hands of the πh9/2-πf7/2 system have been discussed for light odd-A Au nuclei.
