| 摘 要： | 利用严格可解的区分质子和中子的形变平均场加邻近轨道对力模型计算了160—170Er同位素的结合能和奇偶能差,并依此计算了模型中各角动量价核子对在160,162,164Er基态中的占有率.结果显示,偶数角动量价核子对占有率远远大于奇数角动量价核子对占有率,从而说明了S,D,G等偶数角动量价核子对在偶偶核基态中占有主要地位.

| Abstract: | Binding energies and even-odd mass differences of rare-earth 160-170Er nuclei are calculated by using the exactly solvable mean-filed plus nearest-orbit pairing model and compared with the corresponding experimental values.The occupation probability of valence nucleon pairs in a given energy eigenstate is defined and used to calculate the ground state occupation probabilities of valence nucleon pairs with various angular momentum quantum number for 160,162,164Er in the model fitted.The analysis shows that t... |
