| 摘 要： | 在核力的夸克-SU(3)手征场耦合模型基础上研究了N△道耦合效应对NN散射相移的影响. 结果表明N△的5D0分波与NN道的1S0分波间的耦合效应较大,NN的D､F分波与N△道之间的耦合效应较小.

| Abstract: | The coupling effect of (N) channel on the N-N scattering is studied by solving a coupled channel RGM(Resonating Group Method) equation in the quark-SU(3) chiral model. The results indicate that the coupling between 1S0 (NN) and 5 D0 (N) is important in explaining the NN 1S0 phase shifts, and the influence of the (N) channel coupling to the N-N higher partial wave scattering is small. |
