In the present work, 5-fold differential cross sections (5DCS’s) of ionization of H2 molecules by electron impact are computed  as a function of the electron momenta in the final channel of the reaction, and the internuclear orientation, and for both non-dissociative (gerade ) and dissociative (ungerade) final H2+ states. To this end, the two-effective center approximation is employed. It is shown that the interference pattern changes strongly with the final state of the residual molecular ion. Moreover, we compare our calculated cross sections for the dissociative final  H2+ state with new experimental data as a function of the molecular alignment.
