三集团准共振群方法（3QRGM）的进一步研究——N＋^6Li（d＋α）弹性散射的3QRGM分析

A FURTHER STUDY OF QUASI RESONATING GROUP METHOD——ANALYSIS OF p+~6Li ELASTIC SCATTERING WITH 3QRGM

本文对p+^6Li散射，用三集团的略去与双幻核集团交换的共振群方法（3QRGM）作了计算分析。得到的微分弹性散射截面与实验符合甚好，对p+^Li和n+^6Li系统的分析表明：①在低能共振情况，集团效应和交换效应都十分显著地使相移下降，因而很重要；②对含有双幻核的三集团系统，用QRGM对计算更冗繁的严格的RGM来说是一个好的近似；③在QRGM和RGM计算中，适当选到好具有集团结构态的靶核的内部波函数是十分重要的。

In this paper, the elastic scattering of p+~6Li is studied by 3QRGM, a three-cluster RGM omitting the antisymmetrization with the nucleon in the double magic cluster. The main conclusion from studying the systems of p+~6Li and n+~6Li is. the following: The clustering and exchange effects lower the phase shifts conspicuously, hence they are very important in the lower energy region.
