用粒子 转子理论模型计算奇奇核84Y的能谱 ,通过分析能谱的最近邻能级间距分布函数和能谱刚性度的变化特点 ,研究了准粒子特征对奇奇核84Y能谱统计特点的影响 ,发现奇奇核84Y的能谱总体上接近混沌 ;在采用的理论模型中 ,准粒子特征通过反冲项和科氏力作用项影响能谱 ,同时能谱具有随着费米能和能隙参量的减小从接近混沌逐渐转变到接近规则的特点 By using the theoretical model of particle rotor, the energy spectrum of odd odd nuclei 84Y is calculated. By analyzing the variation of energy distribution and the spectral rigidity of the nearest neighbor energy spectrum, the quasiparticle characteristics are analyzed. In the theoretical model adopted, quasiparticle features affect the energy spectrum by the terms of recoil and Coriolis forces, and the energy spectrum has the same frequency as Fermi energy and energy The reduction of the gap parameter changes from near chaos to close to rule
