摘要
总结了可描述大形变原子核运动的Nilsson平均场加推广的对力相互作用的可解模型 .该模型在对力强度较弱的区域仍然以单体和两体相互作用为主 .但随着对力强度的增加 ,高阶相互作用的修正将逐渐变得重要 .通过对同位素154— 171Yb奇偶质量差的数值拟合显示 ,该新模型可说明大形变核的运动规律 .
A Nilsson mean-field plus extended pairing interaction Hamiltonian with many-pair interaction terms is summarized. The investigation shows that one- and two-body interactions continue to dominate the dynamics for relatively small values of the pairing strength. As the strength of the pairing interaction grows, however,higher many-body interaction terms grow in importance. As an example, numerical fits to even-odd mass differences in the 154—171Yb isotopes shows that the new model is applicable to well-deformed nuclei.
