  • Second , the moments of inertia were analysed meticulously , fitted the nucleus experimental data of the a - 130 and 150 regions by using the odd - even differences formula of the moments of inertia , it showed that there was n ' t obvious odd - even differences , while there was obvious odd - even differences in 190 region . these results indicated that pairing correlation in 130 and 150 regions were weaker than 190 region . this conclusion was consistent with the laboratorial one
    ( 2 )对转动惯量进行了较为细致的分析,运用转动惯量奇偶差的公式,拟合a为130和150区的原子核的实验数据,可以看出130和150区并不表现出明显的奇偶差现象,而190区的转动惯量存在着奇偶差,说明130区和150区的对关联比较弱,而190区的对关联比较强,这个结论与实验的结果也是一致的。
