Two-photon laser-assisted electron scattering on hydrogen atom

Abstract

We considered the influence of light-dressed-atom effect on two-photon laser-assisted electron-atom scattering in the Born approximation. We performed calculations for the ground state of a Hydrogen atom. We demonstrated that for small scattering angles, the main contribution to the cross section is made by the combined process, when one of the photons is absorbed by the atomic electron and the second one by the scattered electron. However, in the UV region, when two-photon resonances with highly excited atomic states arise, the main contribution to the cross section is determined by the inverse polarization Bremsstrahlung absorption.

Absolute cross sections of ultra-soft x-ray radiation in electron scattering upon atoms and the soft-photons approximation

“…These conditions are well-known [6][7][8] and are (a) high optical polarizability of atoms (optical breakthrough of alkaline metals was the first experimental proof of polarization BS [26]), or high X-ray polarizability as in Xe atom ( Fig. 1), (b) laser-assisted electron scattering on very small angles [27][28][29] etc.…”

Quantum dynamics of positron-hydrogen scattering and three-body bound state formation with an assisting laser field: predictions of a reduced-dimensionality model

“…Another aspect that motivates the present work stems from the currently growing interest in laser-assisted ion-, electron-, and positron-atom scattering [44][45][46][47][48][49][50]. With the fast development of laser technologies, intense laser fields have become a powerful tool to control and manipulate scattering processes.…”

Coulomb and anomalous magnetic moment effects on laser-assisted electron scattering by atomic nucleus

“…Kornev and Zon [23] have investigated the two-photon laser-assisted electron scattering on hydrogen atom in the first Born approximation. The authors calculated the cross section for electron scattering by hydrogen atom in the ground (1s) state, when one of the photons is absorbed by the atomic electron and the second one by the scattered electron.…”
