ELLIPTICALLY POLARIZED LASER-ASSISTED ELASTIC ELECTRONHYDROGEN ATOM COLLISION IN COULOMB POTENTIAL

The advancement of laser technology is causing the research field of optics to become more active, and with the help of advancementof technology, more detailed information can be obtained. The primary goal of this work is to calculate differential cross section by using a mathematical model in presence of coulomb potential and elliptically polarized beam with single photon absorption. The developed model shows the differential cross section increases with wavelength and decreases with electron energy with elliptically polarized beam. The differential cross section become maximum at 1.56 radian polarized angle and minimum at -1.56 radian polarized angle. The observation is based on 1.5eV laser photon energy, laser field intensity 1014Wcm−2 , polarized angle 1.56 radian angle, and electron energy 0 to 600eV. Using the born first approximation and the Volkov wave function, the developed equation is obtained. The numerically obtained differential crosssection in this work is approximately 10 −192 to 10 −202 , which is less than the differential cross section obtained by Flegel et al. (2013), which is approximately 10 −172 .
