Rotational Model of Superdeformed Nuclei

  • 摘要: 为处理超变形核的转动谱,提出了一个简单的转动模型,即:冻结振动自由度,把超变形核看成是一个刚性转子.将转动哈密顿量在轴对称陀螺波函数所张开的空间中对角化时,进一步考虑了Signature为好量子数,重新计算了A~190区偶偶核的超变形带,自旋指定与ab公式自旋指定仍然一致.并计算了A~150区152Dy的超变形带,结果也与实验值拟合得很好,但自旋指定与ab公式差异较大.To deal with the SD bands, a single rotational model is proposed, i . e. freeze the degree of vibrational freedom, and regard the SD nuclei as a rigid rotor. Also, the Signature is considered to be a good quantum number . 10 SD bands were calculated, all of the assigned nuclear spins are equal to those determined by ab formula. 190 Hg and 152 Dy were also calculated, but the results of assigned nuclear spins are different to the ones of ab formula.
