Relativistic elastic scattering of hydrogen atoms by positron impact with anomalous magnetic moment effects

Elastic scattering of hydrogen atoms by positron impact is studied at various values of incident positron energy and laser intensities. A discussion of differential cross-sections for positron scattering by hydrogen atoms in presence of laser field is presented along with anomalous magnetic moment of both electrons and positrons fully included. Differential cross sections for electrons and positrons remain almost equal in absence of anomalous magnetic moment effects. A comparison is also made with introduction of anomalous magnetic moment effects of both electrons and positrons. At intensities equal to 0.05 a.u. and above significant discrepancies in differential cross section is found even in first Born approximation.
