在相互作用玻色子模型中引入了一种新方案即 O (6)高阶项来系统研究转动核182 W的能级和电四极跃迁性质,并和传统方案及实验结果进行了对比分析,结果表明新方案也可以描述转动核182 W的结构和性质。研究发现,新方案不但对基带的高激发能级和β带的描述比传统方案更为合理,也可以更合理地描述电四极带间跃迁过程,而传统方案下带间跃迁是禁戒的。
在相互作用玻色子模型中引入瞭一種新方案即 O (6)高階項來繫統研究轉動覈182 W的能級和電四極躍遷性質,併和傳統方案及實驗結果進行瞭對比分析,結果錶明新方案也可以描述轉動覈182 W的結構和性質。研究髮現,新方案不但對基帶的高激髮能級和β帶的描述比傳統方案更為閤理,也可以更閤理地描述電四極帶間躍遷過程,而傳統方案下帶間躍遷是禁戒的。

The structure and property of 182 W nucleus will be investigated in the Interacting Boson Model with a new scheme of O(6) higher‐order term .The energy levels and B(E2) transition values are calculated with two different schemes of SU (3) quadrupole‐quadrupole interaction and O(6) cubic interaction for describing the rotational 182 W nucleus ,also compared with the experimental data .The results show that the new scheme can also describe the experimental low‐lying spectrum reasonably , especially the higher levels of ground band and βband .The results also show that both schemes can describe the experimental intraband B(E2) transitions .However ,for interband transitions ,the re‐sults from O (6) cubic interaction are better than those from SU (3) quadrupole‐quadrupole interac‐tion w hich is fully forbidden .
