The existence of Young-type interference patterns has been recently searched in triple differential cross-sections for single ionization of H2 molecules by electron impact, and theoretically supported by calculations obtained by different models. The appearance of interference effects arising from the two-centre geometry of diatomic molecule. These effects seen in triple differential cross-sections are described by interference factor in analogy with light waves. In this work, we discuss about that the interference factor for molecular structure of H2 may reproduce Young-type interference patterns depending on scattering angle, initial and ejected electron energies in triple differential cross-sections. Differences are expected in the triple differential cross-sections spectra of ejected electrons according to kinematical conditions imposed by scattering angle and electron energy.
