Abstract

The ratio of ionization-excitation to single ionization of hydrogen molecules caused by fast proton impact was measured over a wide velocity range (v = 6-24 au) using the coincidence time-of-flight technique. This ratio, approx. 2%, is independent of the collision velocity at high velocities. It differs from the ratio of total H⁺ to H₂⁺ production mostly due to a large contribution from the dissociation of the electronic ground state of the molecular ion. The dissociation fraction of H₂⁺ (1sσ) was measured and compares well with our calculations using the Franck-Condon approximation.
