| 摘 要： | 在单粒子势模型的框架下,通过在核中心势中引入l2修正项(l表示核子的轨道角动量),计算了A=11同质异位素核的均方根半径值、能级值和密度分布.理论计算得到的半径值和能级结构与实验结果一致.特别是,理论计算能够同时实现镜像核11Be和11N中251/2-1p1/2能级间的反转,从而解释了11Be和11N的反常的自旋宇称值...

| Abstract: | In the framework of the single-particle potential model,the level structures of A=11 isobars are investigated by introducing an l2 modification in the nuclear potentials.The theoretical results of rms radii and level structures agree with the known experiments.Especially,the calculations reproduce the 2s1/2-1p1/2 level inversions in 11Be and 11N,which are in keeping with their abnormal spin-parity values.In addition,the study manifests that the ground state of 11Li is two-neutron halo state,the ground-state and the first-excited state of 11Be are one-neutron halo states. |
