Electron interference signatures present in fully differential cross sections for single ionization by 6 MeV protons in H2 molecules are investigated. We employ a molecular version of the continuum-distorted wave-eikonal initial state model, where all the interactions present in the exit channel are considered on an equal footing. Calculations of fully differential cross sections are performed for different electron and projectile kinematical conditions and the range of validity of the theoretical approach is discussed. Furthermore, we explore the presence of interference patterns in differential cross sections for both aligned and randomly oriented targets in asymmetric coplanar geometries. continuum-distorted wave-eikonal initial state model, where all the interactions present in the exit channel are considered on an equal footing.
