摘要：应用玻恩一阶近似理论,在电子入射方向平行于激光场的极化方向的特殊散射模式下,利用光学势模型研究了激光场中电子-氩原子散射问题。利用静电屏蔽势,应用第二玻恩近似公式对双模激光场中电子-氩原子散射进行了计算。在相位不同、散射截面出现关于ν=0对称和镜面对称的情况下,这个理论方法给出了较好的结果。
Born approximation theory of the first order in the electronic parallel to the direction of the incident laser polarization direction of this particular scattering mode, the use of laser optical potential model in the field of electronic argon atom scattering was studied. Potential use of static shielding, the second Born approximation of the formula in the field of electronic dual-mode laser argon atom scattering is calculated. Phase of a cross section of different symmetry and mirror symmetry, and this theory is presented with good results.
