Sm奇核形状相变:有效序参量和奇偶效应

Shape phase transition in the odd Sm nuclei: effective order parameter and odd-even effect

Yu Zhang, Xin Guan, Yin Wang, Yan Zuo, Li-na Bao, Feng Pan

摘要:

用与束缚能有关的一些量作为有效序参量,分析了奇Sm核的形状相变。发现奇Sm核的相变信号比偶Sm核的明显增强。进一步的分析表明,Sm核中与配对有关的跃迁行为可以用平均场加配对相互作用模型来描述,配对强度$G$单调下降.

英文摘要:

Some binding-energy-related quantities serving as effective order parameters have been used to analyze the shape phase transition in the odd Sm nuclei. It is found that the signals of phase transition in the odd Sm nuclei are greatly enhanced in contrast to the even Sm nuclei. A further analysis shows that the transitional behaviors related to pairing in the Sm nuclei can be well described by the mean field plus pairing interaction model, with a monotonic decrease in the pairing strength $G$.
