摘要
用能量为95 MeV 的^(13)C 束流,轰击天然厚 Ba 靶,对^(146)Sm 的高自旋态进行了实验研究,观测到17条新的γ射线和11条新能级,能级纲图延伸到了激发能为10.3 MeV 处,在此高激发能区,能级结构仍呈现粒子组态的特性,没有发现长寿命的同质异能态.
High spin states of ^(146)Sm have been experimentally studied by using ^(13)C (95 MeV) beam bombarding natural Ba target.Seventeen new γ-rays and eleven new levels were found and assigned to the level scheme of ^(146)Sm which extends up to 10.2 MeV excitation energy.Level structure still shows the characteristics of particle configurations.No long-lived high spin isomer was found up to such high excitation region.
