壳模型对143Pm核跃迁几率的计算
Using NSM to Calculate Transition Rates of 143Pm
【摘要】 原子核跃迁几率理论计算和实验对比是分析描述原子核内部结构的主要手段之一。目前采用重离子核反应观测到143Pm核(Z=61,N=82)高自旋能级结构:激发态最大能级达Ex=8 397.6keV,对应自旋J=47/2(=1)。利用核壳模型在计算143Pm核能级结构及对应的自旋宇称基础上,系统地对其γ级联跃迁链以及纯E2跃迁进行了计算,并与实验数据进行对比。采用OXBASH程序的单粒子跃迁公式计算了143Pm的跃迁几率。
【Abstract】 At present,the high spin state of 143Pm(Z=61,N=82) have been investigated.The level scheme of 143Pm has been extended up to an excitation energy Ex=8 397.6 keV and spin J=47/2(=1).Based on the nuclear shell model(NSM),we have calculated the sequences of γ-ray transition rates and the pure E2 reduced transition probabilities of143Pm,and compared with experimental data.The formula of single-particle transition probability in the OXBASH code was applied in this paper.
