原子核能谱的Staggering现象与四极相互作用

Staggering Phenomenon In Nuclear Energy Spectrum and Quadrupole-Quadrupole Interaction

本文描述了质子-中子相互作用玻色子模型(IBM2)中原子核能谱的Stag-gering现象的改善方案,并利用这一方案对Ru和Pt同位素偶-偶核计算的结果,分析和讨论了原子核能谱的Staggering现象与四极-四极相互作用的关系。

An improved treatment on staggering phenomenon in nuclear energy spectrum in the framework of IBM2 is described in this paper, The kQ_π^(2)·Q_v^(2)+k′(Q_π^(2)·Q_π^(2)+ Q_v^(2)·Q_v^(2)) hamiltonian is introduced to treat the even-even isotopes of Ru and Pt. The relation between the staggering phenomenon and the quadrupole-quadrupole inte- raction is discussed.
