中文摘要：

利用严格可解的Nilsson平均场加邻近轨道对力模型,在区分质子和中子情况下,研究了大形变核的性质,主要计算了中子数为N=94的同中异质素的结合能、奇偶能差和转动惯量,并与相应的实验值进行了系统比较,结果表明此模型可以合理描述这些性质,正确反映原子核奇偶性质的变化规律。然后以偶偶核^160Dy为例,研究了基态中各角动量J=0,1,...,12价核子对的占有率。结果表明,偶角动量占有率远高于奇角动量占有率,其中S,D,G价核子对各组份在基态波函数中是主要的。

英文摘要：

The Nilsson mean-field plus the nearest orbit pairing model for deformed nuclei is applied to investigate systematically the properties of the N = 94 nuclei, employing both proton-proton and neutron-neutron pairing interactions. The binding energies, even-odd mass differences, moments of inertia are calculated and compared with the corresponding experimental data. The results show that this model can reasonably describe these properties. Further, the ground-state occupation probabilities of valence nucleon pairs with angular momentum J = 0, 1,..., 12 for even-even ^160Dy are calculated, and the results show that it is much higher for the even angular momenta than the odd angular momenta,and the S, D, G components in the ground-state wave function are dominant.
