超形变原子核全同带的判断与角动量增量顺排量子化

Criterion of Identical Bands and Quantization of Incremental Alignments in Superdeformed Nuclei

给出了一个新的从能量角度判断超形变带全同带的方法，并运用这种方法分析了100多条超形变带．给出了全同带数目随判断参数的变化关系．还引进了量子化区间的概念，从统计角度分析角动量增量顺排的量子化问题，得出了全同带增量顺排随判据加严而趋向于量子化的性质，而正常形变全同带则不具有这一性质．讨论了新方法与粒子转子模型之间的关系．

A new method used to select identical bands is given from the energies.More than one hundred superdeformed bands were analysed by this method, and many identical bands were found. A concept of quantized region is used to analyse the quantization of incremental alignments. It is pointed out that the quantization of incremental alignments strongly depends on the criterion of selecting identical bands.The relation between particle-rotor model and the selection method is also revealed.
