Electron's anomalous magnetic moment effects on electron-hydrogen elastic collisions in the presence of a circularly polarized laser field

摘要

The effect of the electron's anomalous magnetic moment on the relativisticelectronic dressing for the process of electron-hydrogen atom elasticcollisions is investigated. We consider a laser field with circularpolarization and various electric field strengths. The Dirac-Volkov statestaking into account this anomaly are used to describe the process in the firstorder of perturbation theory. The correlation between the terms coming fromthis anomaly and the electric field strength gives rise to new results, namelythe strong dependence of the spinor part of the differential cross section(DCS) with respect to these terms. A detailed study has been devoted to the nonrelativistic regime as well as the moderate relativistic regime. Some aspectsof this dependence as well as the dynamical behavior of the DCS in therelativistic regime have been addressed.
