DIFFERENTIAL CROSS-SECTION OF THE DISSOCIATIVE IONIZATION OF H-2(-ELECTRON IMPACT() BY FAST)

The differential cross section of the dissociative ionization of H-2() by electron impact is determined theoretically using a model which s eparates the two scattering centres of the molecule. A coincidence det ection of the two outcoming electrons and one of the H+ is supposed Th e effect of the direction of the molecular axis on the seven-fold diff erential cross section (7DCS) of this reaction is studied for the case s of large and small values of the impact parameter. The variation of the 7DCS, in terms of the scattering angle for a fixed direction of th e internuclear axis, reveals an interesting analogy with light interfe rence patterns with the two scattering nuclei playing the role of the two pin holes of the Young's experiment.
