ANGULAR-DISTRIBUTION OF PHOTOELECTRONS EMITTED AT PULSE LASER IRRADIATION

The analysis of electron-distribution formation in a metal irradiated with a laser pulse is given on the basis of the explicit solution of t he quantum kinetic equation. The angular distributions of electrons em itted under laser irradiation of a metal surface are associated with t he non-Fermi electron distribution generated by the laser action. The anisotropy of photon absorption in an electron-phonon collision causes a two-leafed distribution structure, which qualitatively distinguishe s this mechanism of laser-stimulated electron emission.
