核子-核子相互作用中由六夸克集团激发引起的关联效应

CORRELATED EFFECT ARISEN FROM EXCITATIONS OF SIX-QUARK CLUSTERS IN NUCLEON-NUCLEON INTERACTION

本文在RGM的框架下,研究了核子-核子相互作用中由六夸克集团激发引起的关联效应,分析了它对~1S_0态的相对运动波函数的影响.结果表明,六夸克集团效应在两核子间距离为1fm附近最强,在大于2fm后可忽略不计,它把核子之间的相对运动波函数在R_N小的地方向外推了一些,同时加大了1fm附近的振幅.

The correlated effect arisen from excitations of six-quark clusters in the nucleon-nucleon interaction is studied in the RGM framework and the six-quark configuration effect on the wave function of the relative motion in ~1(?) state is analyzed. It is shown that this effect is strong around 1 fm and negligible at the distance longer than 2 fm. Moreover, this effect pushes the wave function of the relative motion between nucleons outward in some extent in the small R_N region and enhances the amplitude of the wave function around 1 fm.
