根据原子分子碰撞过程确定原子与分子之间的相互作用势是一种比较理想的途径.改进后的MS势能形式是一种形式比较简便、表达函数统一、能够准确描述系统相互作用特征的势能形式.基于MS势模型得到了He-HCl体系相互作用势,计算出了各种微分散射截面、分波截面,从而得到了有关相互作用的重要信息.
It is a real way to determine the interaction energy between the atom and molecule according to the atomic and molecular collision process.The modified MS potential can accurately and tersely describe interaction energies of the system.Potential energy of He-HCl is obtained based on MS potential.The differential cross section,partial cross section,and total scatter section are also calculated.
