In the present work, we investigate the ionization of hydrogen molecules by fast electron impact. In particular, we study the interference phenomenon which may appear as consequence of the coherent emission from the two indistinguishable centers of the molecule. Interference patterns are predicted in the ejected electron spectra corresponding to multiple differential cross sections. Moreover, recent experimental interference evidence is presented for the case of single ionization of the D2 targets by electron impact.
