Laser assisted proton collision on light nuclei at moderate energies

TL;DR

This paper develops an analytic model for laser-assisted proton scattering on light nuclei, accounting for multiple photon absorption, and applies it to proton-Carbon collisions at moderate energies with varying laser intensities.

Contribution

It introduces a new analytic angular differential cross section model for laser-assisted proton-nucleon scattering including nth-order photon absorption.

Findings

Cross sections calculated for proton-12C collisions at 49 MeV.

Laser intensities range from 10^7 to 10^21 W/cm^2, approaching relativistic regimes.

Model captures effects of multiple photon absorption on scattering cross sections.

Abstract

We present analytic angular differential cross section model for laser assisted proton nucleon scattering on a Woods-Saxon optical potential where the nth-order photon absorption is taken into account simultaneously. As a physical example we calculate cross sections for proton - $^{12}$C collision at 49 MeV in the laboratory frame where the laser intensity is in the range of $ 10^{7} - 10^{21}$ W/cm$^2$ at optical frequencies. The upper intensity limit is slightly below the relativistic regime.
