The absolute differential cross sections of e-Ar scattering in laser field are calculated employing the second Born approximation with the static screen potential including polarization potential and the single static screen potential in the special scattering geometry that the incident electron beam is parallel to the polarization direction of laser field. The second Born approximation gives better results than the low-frequency whem formula when compared with the experimental data, and it is found that the electron-atom polarization potential plays an important role in laser-assisted electron-atom scattering.
