| Résumé : | The influence of a strong laser field on the dynamics of fast (e, 2 e) collisions in helium is analyzed in the asymmetric, coplanar geometry. The interaction of the laser field with the incident, scattered and ejected electrons is treated in a non-perturbative way, while the remaining interactions are treated by using first order perturbation theory. Detailed calculations are performed for an incident electron energy Eki=600 eV, an ejected electron energy EkB=5 eV and a scattering angle θA=4°. The influence of the laser parameters (photon energy, intensity and direction of polarization) on the angular distribution of the ejected electron is analyzed. We find that in general the triple differential cross sections are strongly dependent on the dressing of the projectile and the target by the laser field. © 1992 Springer-Verlag. |
