摘要
在s－dIBM1的O（6）极限下，引入d玻色子之间相互作用的等效三体势，考虑f玻色子产生的八极态，导出了正负宇称态能谱解析表达式，并对过渡区偶偶核118Xe、120Xe进行了能谱计算，得到了与实验能谱符合更好的结果，然后用Staggering指数定量分析了正负宇称态能谱中的Staggering现象．
Within the O(6) limit of s-d IBM1, the effective three-body potential between the interactions of d-bosons is introduced with the consideration of octupole states, which are produced by a f-boson plus (N-1) s-d-bosons. Then the analytic expressions of positive and negative parity energy spectrum formula are obtained. Also the energy spectra of even-even nuclei 118 Xe and 120 Xe are calculated. Good fits with the experimental data are obtained, and Staggering phenomena is quantitatively analyzed with Staggering index formula.
