【摘要】 运用独立原子模型 ( IAM) ,在入射电子能量 2 0 0～ 1 0 0 0 e V范围内 ,我们第一次计算了电子与 SO2分子碰撞的弹性微分散射截面 ( DCSs) .目前结果与可行的实验数据进行了比较 ,并得到较好一致 .原子的弹性散射振幅及微分散射截面由光学势模型得到 .更多还原

【Abstract】 The elastic differential cross sections(DCSs) for electron scattering from SO 2 are firstly calculated at 200～1000eV employing the independent atom model (IAM) with partial waves.The atoms are presented by a model complex optical potential,which is composed of static,exchange,polarization,and absorption terms.Compared with available experimental data the present approach gives good results.更多还原
