【摘要】 本文从夸克集团模型出发,由夸克互作用势求两核子系统的平均势能,在绝热假设近似下导出了核子——核子互作用等效势;选用唯象夸克势(线性禁闭势和二次禁闭势)计算N—N中心势;采用玻恩近似法计算S分波相移;所得结果与单交换势及Harvey.Oka.Yazakl等人的结果进行了比较,短程处得到较强排斥力。更多还原

【Abstract】 In this paper, based on the nonrelativistic quark cluster model we find average potential of two nucleons system. By means of adiabatic supposition approximation, the equivalent potential of N-N interaction is derived from the phenomenological quark potential, using the phenomenological quark potential (linear or quadratic confinement potential),the central potential of N-N interaction is caculated in the four channels. By means of Born approximmation from the phase shifts, the phase shifts of N-N scaffing in the two channels is caculated. Theses results are compard with oper, and the rusults given by Harvey Oka and Yazakl, there is a strong, repulsive force a short distance.更多还原
