摘要/Abstract

摘要：计算了核子- 核子散射的总相移, 包括夸克- 胶子交换的总的相移、夸克- 胶子瞬时势的贡献以及单, 双交换提供的总的相移. 相移的计算值与实验结果的比较曲线表明它们是一致的, 同时表明夸克- 胶子交换作用在核子相互作用中起重要作用, 尤其在近程范围内.

关键词： 散射相移, 夸克- 胶子交换, 单交换, 双交换

Abstract: The total N- N scattering phase- shifts are calculated , including the total phase- shifts of quark- gluon exchange potential, the phase- shifts of quark- gluon exchange instantaneous potential as well as the total phaseshifts of one- ?? and two- ?? exchange potential.The comparison of the calculation of phase- shift with the experimental result shows that they are consistent with each other and that quark- gluon exchange plays an important role in the
N- N interaction, expecially in the short range.

Key words: scattering phase- shifts, quark- gluon exchange potent ial, one- pion and two- pion exchange
