摘　　要：对惰性气体原子与氘分子系统建立T-T势能模型,并采用密耦近似方法,计算了原子入射能量分别为0.05、0.10、0.15、0.20、0.25eV情况下,系统00-00弹性碰撞微分截面及00-02转动激发微分截面.通过对计算结果的分析得到了弹性及非弹性碰撞微分散射截面随角度的变化规律以及入射原子能量和系统约化质量对微分截面的影响.In this paper,close-coupling approximation and T-T potential model are applied to the He,Ne,Ar,Kr,Xe-D2 systems.The differential cross sections of 00-00 elastic collisions and 00-02 inelastic collisions with collision energy E =0.05,0.10,0.15,0.20 and 0.25 eV have been calculated.By analyzing the calculation results,the change rule of the differential cross sections with the increase of angles and the influence of the energy of incident atoms and the reduced mass of systems on these sections have been obtained.
