激光场中电子碰撞氢原子电离三重微分截面

THE TRIPLE DIFFERENTIAL CROSS SECTION FOR e-H IMPACT IONIZATION IN A LASER FIELD

本文用CPB(Coulomb-Projected Born)近似和GCPB(Generalised Coulomb-Projected Born)近似对激光场中电子与氢原子碰撞电离的三重微分截面及平均吸收或发射光子数进行了计算,并将结果与P.Cavaliers等(1980)的Born近似结果进行了比较。

The triple differential cross section for the electron impact ionization of Hydrogen atom in the presence of a laser field is calculated in the Coulmb-projeet Born approximation and generalised Coulmb-project Born approximation and detailed comparison is made with the ordinary Born result.
