奇质子核K＝1／2带的带交叉

Bandcrossing of K = 1/2 Bands in Odd - Proton Nuclei

从粒子一转子模型分析了奇Ａ核Ｋ＝１／２带的带交叉．脱耦合项的出现可引起回弯频率异常．在［５４１］↓的情况下，造成的回弯推迟可与实验观测值相比拟．

The bandcrossing in the K=1/2 bands of odd-A nuclei was discussed in the particle-rotor model.The decoupling term in the rotational energy expression has a remarkable effect on the backbending frequency,which,in the band built on the [541]↓orbital,leads to a bandcrossing delay comparable with the observa tions.
