质子与^(13)C原子核弹性散射动量空间库仑作用的处理

Treatment of Coulomb Interaction in Momentum Space for Proton-^(13)C Elastic Scattering

将C M Vincent和S C Phatak,以及R Crespo和J A Tostevin分别提出的两种不同的处理库仑作用的方案,推广应用于自旋12×21的散射,研究了P-13C弹性散射动量空间库仑作用的处理。计算了入射质子能量为500M eV时的微分散射截面和极化本领。两种方案的结果相比较表明,R-J方案在散射角较大处比V-P方案有较好的修正效果;两种方案均显示库仑作用产生的影响是小的。

By applying two methods proposed respectively by R Crespo and J A Tostevin and by C M Vincent and S C Phatak to p-13C elastic scattering,we studied the treatment of coulomb interaction in momentum space.The differential cross section and polarization at 500MeV are calculated.The present results show R-J method is better than V-P method at places of large scattering angle.Two methods show that the influence of coulomb interaction is less obvious.
