摘　　要：采用微观的动量空间光学势及R.Crespo和J．A．Tostevin建议的处理动量空间库仑作用的方法，计算了500MeV的核子与镜象核3H和3He弹性散射微分截面，截面比r1，r2和超比R．理论计算结果r1，r2和R均不等于1，显示出由于p-核库仑作用直接引起的电荷对称破坏效应．Using a microscopic momenteum space optical potential and the method for treating the Coulomb force, which is propose by R Crespo and J. A. Tostevin, we calculated the differential cross section of elastic nucleon scattering from the 3H and 3He mirror nuclei at 500MeV and the ratio of cross sections. The charge symmetry breaking effects due to the Coulomb force between the proton and nuclei are shown.
