Primary and secondary interference structures attributed to coherent electron emission from the identical atomic centers of H{sub 2} have been observed in the velocity distributions of ejected electrons resulting from (1-5)-MeV H{sup +} impact. The primary interference structures are found to depend on the projectile velocity, in addition to the previously observed dependence on electron ejection angle. In contrast, the secondary structures, attributed to intramolecular scattering, do not change with projectile velocity and show only slight variations with the electron ejection angle. The data also provide evidence for significantly higher-frequency structures for which no explanation currently exists.
