Popis: We have measured fully differential cross sections for electron capture in 75 keV $p+{\mathrm{H}}_{2}$ collisions with subsequent dissociation of the intermediate molecular ${\mathrm{H}}_{2}^{+}$ ion by vibrational excitation using different projectile coherence lengths. Data were obtained for two molecular orientations as a function of projectile scattering angle. Two types of interference, single- and molecular two-center interference, were identified. The two-center interference structure is phase shifted by $\ensuremath{\pi}$ compared to what we expected. Furthermore, the presence of projectile coherence effects could be reconfirmed.
