| 摘 要： | 采用粒子数守恒方法,对推转壳模型(j=11/2)进行了精确计算,详细分析了转动原子核中对转移矩阵元随转动频率的变化.与粒子数投影的Hatree-Fock-Bogoliubov方法导出的结论相反,“diabolic对转移”现象仅出现在高激发带,而晕带到晕带的对转移矩阵元则变化较为缓慢,并不出现振荡现象.

| Abstract: | The exact treatment for the cranked single-j shell model Hamiltonian using the particle-number conserving method and the systematic analysis for the .pair transfer matrix element in rotating nuclei have been done. In contrast to the previous conclusion drawn from the usual Hatree-Fock-Bogoliubov(HFB) method or the number projected HFB treatment, for the pair transfer matrix element from the yrast band to yrast band, a smooth and slow variation with co is observed and no oscillation behavior occurs. But diabolic pair transfer is expected to occur in some higher excited bands. |
