应用一阶玻恩近似理论,分别利用Yukawa势、静电屏蔽势及光学模型势对双模激光场中电子-氩原子散射的微分散射截面进行了研究计算.从计算结果可以看出,极化和交换效应在散射过程中起着重要作用,同时也表明光学模型势能够准确的描述激光场中的原子势场.
The differential cross sections of e-Ar scattering in the bichromatic laser field are calculated employing the the first Born approximation with Yukawa potential,static screen potential and optical model potential,respectively.These results show that polarization and exchange effects are important in the scattering and the optical model potential may give the better description for atomic potential in bichromatic laser field.
