Abstract
The differential cross section of the dissociative ionization of H2+ by electron impact is determined theoretically using a model which separates the two scattering centres of the molecule. A coincidence detection of the two outcoming electrons and one of the H+ is supposed. The effect of the direction of the molecular axis on the seven-fold differential cross section (7DCS) of this reaction is studied for the cases 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 the internuclear axis, reveals an interesting analogy with light interference patterns with the two scattering nuclei playing the role of the two pin holes of the Young's experiment.Keywords
