摘要
利用重离子熔合蒸发反应124Sn(7Li,3n)布居了双奇核128I的激发态.基于标准在束γ谱学实验测量结果,扩展并更新了128I原有能级纲图.根据已有的高自旋态核结构知识,通过系统学比较和分析,指出了基于π(g7/2/d5/2)vh11/2组态的负宇称能级结构和πh11/2πh11/2组态的正宇称能级结构.
High-spin states in doubly odd 128I have been investigated via the 124Sn(7Li,3n) fusion-evaporation reaction.Detailed analysis of γ-γ coincidence relationships leads to a revised high-spin level scheme for 128I.The negative-parity structure based on the π(g7/2/d5/2)πh11/2 configuration as well as the positive-parity structure based on the πh11/2πh11/2 configuration have been assigned according to level spacing and excitation energy systematics as well as the existing knowledge of neighboring odd-mass and odd-odd nuclei.
