摘要
利用有效索末菲参数来考虑三体耦合效应,计算了非共面几何(垂直平面与垂直动量转移平面)条件下,102 eV的电子碰撞He单电离反应的全微分截面,并将其计算结果与三库仑波模型、二阶扭曲波近似、我们前期的理论结果及实验数据进行了比较.
Following the work of Z Chen (1997 Phys. Rev. A, 56. R2514), three-body coupling effects are considered by the introduction of effective Sommerfeld parameters for non-coplanar geometry. The fully differential cross sections for electron impact ionization of helium at incident energy of 102 eV in the non-coplanar geometry are calculated. Results of this approach are compared with the experiment, the DWB2, 3C and our earlier results.
