Luminescence cross sections in the low-energy collisions of H+, H2+, and H3+ ions with H2
Ryszard Drozdowski , Andrzej Kowalski
AbstractLuminescence cross sections for the optical emission of molecular hydrogen in the 200–600nm spectral range and for the atomic Balmer-βline were measured for low-energy (≤1 keV) H+, H2+, and H3+ ions colliding with H2 gas targets. Molecular hydrogen transitions between singlet states were observed for all the systems studied, while the emission continuum H2 (a-b) and discrete spectra associated with other transitions between triplet states appeared only in the H2++ H2 collisions, where the spin conservation rule is fulfilled. Isotopic substitutions in the H2+/D2++ H2, D2 system show that at E lab = 1 keV, a dominant molecular luminescence mechanism is the collision-induced excitation (CIE) of the target.
