The existence of Young-type interference patterns, recently measured [N. Stolterfoht et al., Phys. Rev. Lett. 87, 023201 (2001)] in double-differential cross sections for single-electron ionization of H2 molecules by ion impact, is theoretically supported by calculations obtained using a molecular distorted-wave model introduced here. The importance of adequately describing the target as a molecule is emphasized. The contributions from direct and interference terms are separated.
