摘要
本文采用内禀凝聚态方法,取消IBM2中通常采用的最大F旋截断近似,对变形核,用内禀凝聚态及其内禀激发来描述低能集体转动态。按照这种理论方法计算了^(168)Er的低能转动能谱。结果表明,对于激发带,最大F旋截断近似很不好。对中子玻色子和质子玻色子的内禀激发是分别进行的。
By the intrinsic condensate method, an attemption is made to cancel the maximum F-spin truncation approximation usually adopted in IBM2. In the region of deformed nuclei, the in- trinsic condensate and its intrinsic excitations are used to describe the low-lying collective rota- tional states. Using this method. the low-luing spectrum of ^(168)Er are calculated. The result show that the maximum F-spin truncation approximation become bad for the excitational ban- ds, and the intrinsic excitations of neutron boson and proton boson are mutual separated.
