Jahn-teller interactions in the dissociative recombination of H3+

Abstract:
A simple analytical approach is presented to describe the dissociative recombination (DR) of an electron with H3+ and its isotopomers. The principal assumption is that resonant capture mediated by the Jahn-Teller interaction dominates the cross section. The only input required comes from spectroscopic data on the 3pE;{'} Rydberg state of H3 and the nu_{2} vibrational frequencies of H3+ and its isotopomers. The approach provides an independent prediction of the low-energy DR cross sections and rates, and is in good agreement with the latest experimental and theoretical determinations.
