| 摘 要： | 利用NUSHELLX球形壳模型程序, 考虑两种不同组态空间下94Tc的能级结构. 计算结果表明, 94Tc的正宇称自旋态激发机制主要为p1/2轨道质子跨越Z=40亚壳向高jg9/2轨道跃迁, (f5/2,p3/2)轨道质子跨越Z=38闭壳向(p1/2,g9/2)轨道激发, 负宇称自旋态为d5/2轨道中子跨越N=56亚壳向(g7/2,h11/2)轨道激发.

| Abstract: | Using the NUSHELLX spherical shell model program, we consideredthe level structure of 94Tc under two different configuration spaces. The calculation results show that the excitation mechanism ofpositive parity spin states of 94Tc is dominated by the excitation of protons from the p1/2 orbitinto the jg9/2 orbit across the Z=40
subshell closure and protons from the (f5/2,p3/2) into the (p1/2,g9/2) orbit across the Z=38 subshell closure. The negative parity spin statesare the excitation of neutrons from the d5/2 orbit into the (g7/2,h11/2) orbits across the N=56 subshell closure. |
