基于壳模型分析^(94)Tc能级结构

Analysis of Level Structures of ^(94)Tc Based on Shell Model

利用NUSHELLX球形壳模型程序,考虑两种不同组态空间下^(94)Tc的能级结构.计算结果表明,^(94)Tc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,(f_(5/2),p_(3/2))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.

Using the NUSHELLX spherical shell model program,we consideredthe level structure of 94 Tc under two different configuration spaces.The calculation results show that the excitation mechanism ofpositive-parity spin states of 94 Tc is dominated by the excitation of protons from the p 1/2 orbitinto the jg 9/2 orbit across the Z=40subshell closure and protons from the(f 5/2,p 3/2)into the(p 1/2,g 9/2)orbit across the Z=38 subshell closure.The negative-parity spin statesare the excitation of neutrons from the d 5/2 orbit into the(g7/2,h 11/2)orbits across the N=56 subshell closure.
