Fully Differential Study of Capture with Vibrational Dissociation in p+ H2 Collisions

We have measured fully differential cross sections for electron capture in 75 keV p+H2 collisions with subsequent dissociation of the intermediate molecular H2+ ion by vibrational excitation using different projectile coherence lengths. Data were obtained for two molecular orientations as a function...

Sumario:We have measured fully differential cross sections for electron capture in 75 keV p+H2 collisions with subsequent dissociation of the intermediate molecular H2+ 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 π compared to what we expected. Furthermore, the presence of projectile coherence effects could be reconfirmed.
