【摘要】 在Eikonal多次散射理论的框架下,探讨了库仑效应对π^±-⁴⁰Ca弹性散射的影响。我们采用FORTRAN 77编制程序,对反应微分截面作了数值计算,理论结果与实验数据符合得很好。结果表明,库仑效应不仅提高了小角度处的微分散射截面的值,而且起了填充微分散射截面曲线极小谷的作用,从而使理论计算结果与实验进一步吻合。更多还原

【Abstract】 Within the framework of Eikonal multiple-scattering theory, the Coulomb effect in π±-40Ca elastic scattering is studied. The calculating program for the differential cross section is worked out by FORTRAN 77 and the results are in good keeping with the experimental data, indicating that the Coulomb effect does not only enhance the small angle differential cross section, but also fill up the dips of differential cross section.更多还原
