摘要: The effect of the electron’s anomalous magnetic moment on relativistic electronic dressing for process electron-hydrogen atom elastic collisions is investigated. We consider a laser field with circular polarization and various electric strengths. Dirac-Volkov states taking into account this anomaly are used to describe in first order perturbation theory. correlation between terms coming from strength gives rise new results, namely strong dependence spinor part differential cross section (DCS) respect these terms. A detailed study has been devoted non regime as well moderate regime. Some aspects dynamical behavior DCS have addressed.
