摘要
本文通过用BCS方法对稀土区变形偶-偶核的内禀十六极矩(Q_(40))随质量数的变化规律的研究,表明了对关联对于解释这种变化规律是十分重要的。对内禀系中Cooper对的分析表明,角动量为4的核子对(G对)的成份虽然不大,但其对Q_(40)的贡献是十分重要的.
In this paper, BCS method is applied to reproduce the mass-number dependence on the intrinsic hexadecapole moments (Q_(40)) of deformed even-even nuclei in the rare earth region, and it is shown that the pair correlation is an important factor for explaining such a dependence. The analysis of the intrinsic Copper-pair shows that the nucleon pairs with angular momentum equal to four (G-pairs) make a considerable contribution to the intrinsic hexadecapole moments although the component of such pairs is small.
