Resumen:
The presence of interference patterns in doubly differential cross sections is investigated for
single electron ionization of a heteronuclear system, the HeH+ molecular ion, produced by
highly energetic protons. These interferences, which are due to coherent electron emission
from the vicinity of the target nuclei, are preserved even after averaging over all molecular
orientations. However, when compared with the homonuclear H2 target case, the effect appears
to be less pronounced due to the partial localization of the target electrons around the alpha
particle centre. Similarities and differences with the case of photon beams are also discussed.
