Free-free Transition in Presence of a Resonant Bichromatic Laser Field
-
摘要: 研究了双色共振激光场中电子原子碰撞的自由 自由跃迁过程 利用三能级模型和旋转波近似得到了靶原子的波函数 ,在波恩近似的基础上进一步导出了多道碰撞的微分截面公式 利用此公式计算了共振激光场中的激发碰撞对整个的碰撞贡献. We investigate the free-free transition in the presence of the resonant bichromatic laser field. The target atom is described by the three-level model and the rotating wave approximation. The differential cross section for a multi-channel collision is derived. The calculations show that excitation collision has quite small contribution to the whole collision pr ocesses.Abstract: We investigate the free-free transition in the presence of the resonant bichromatic laser field.
