L'étude de l'ionisation dissociative des systèmes diatomiques par impact électronique

Abstract : The multiply differential cross section of dissociative ionization (e,2e) of H+2 and double ionization (e,3e) of H2 by fast (2-10keV) electron impact is determined theoretically using a two-center continuum wave function for slow (50eV) ejected electron satisfying the correct boundary conditions. The influence of the orientation of the internucleair axis as well as the role of the momentum transfer and the shared recoil momentum between the tow nuclei are studied to find the optimal conditions for experimental detection
