Eletron-helium laser-assisted free-free scattering for incident energies from 30 - 200 eV: effects of polarization direction

[摘要] We report on experiments that examine electron-helium scattering in the presence of an Nd:YAG laser field of 1.17 eV photons. At each incidentelectron energy (30, 60, and 200 eV), the laser polarization direction is varied within a plane perpendicular to the Watson approximation calculations.
