Laser-Induced Multiphoton Processes ine−−pScattering

Abstract

In order to obtain information about the role of multiphoton processes in recently reported laser-induced nuclear fusion, the cross section for simultaneous net absorption of $n$ photons by a system of two point charges has been calculated numerically for $e^{-}-p$ scattering in a ruby laser beam at an incident relative energy of 100 eV. The results show that at laser intensities involved in fusion experiments multiphoton processes apparently play an important role, partly contributing to the same order within certain $n$ intervals.
