Electron-atom Scattering in Multi-chromatic Laser Field
-
摘要: 利用微扰理论对多模激光场中电子 原子散射进行了初步研究 .在激光场的极化方向平行于入射电子方向这种特殊的散射模式下 ,计算得到了电子 原子微分散射截面与激光场的相移、交换光子数之间的关系 .结论和其它相关理论是一致的.Electron scattering from atom in multi-chromatic laser fie ld is investigated by employing the perturbation theory. The relations of differen tial cross sections of e-atom scattering, phase and commucative photon are obta ined in a special scattering geometry(the incident electron beam is parallel to the polarization direction of the laser field). Our results are consistent with other correlative theories.Abstract: Electron scattering from atom in multi-chromatic laser fie ld is investigated by employing the perturbation theory.
