本文中用夸克模型,Warke近似,并作为补偿,在夸克唯象势中加入中程势(-1)T+JKre(-r/a2),计算了π-N相互作用势,从此势计算了L2T,2J=S11,S31,P11,P31,P13和P33六种道的相移。在入射π介子动能Eπk(lab)=0—700MeV范围内,与由实验方法决定的相移进行了比较。By means of quark potential model and Warke approximation, and introducing as compensation intermediate potential (-1)T+JKre(-r/a2) in the phenomenological one gluon exchange quark interaction potential, the pion-nucleon interaction potential is calculated. The phase shifts of p-N scattering in the six channels S11, S31, P11, P31, P13, P33 are determined for the incident pion kinetic energy in the laboratory coordinate system up to 700 MeV. These results are compared with the experimentally determined phase shifts.
