Theory of dissociative recombination of highly-symmetric polyatomic ions

POSTER

Abstract

A general first-principles theory of dissociative recombination is developed for highly-symmetric molecular ions and applied to H$_3$O$^{+}$ and CH$_3^+$, which play an important role in astrophysical, combustion, and laboratory plasma environments. The theoretical cross-sections obtained for the dissociative recombination of the two ions are in good agreement with existing experimental data from storage ring experiments.

*We would like to thank Ioan Schneider for attracting our attention to study H$_3$O$^+$ and CH$_3^+$. This work has been supported by the NSF and DOE. VK also acknowledges support from the RTRA network {\it Triangle de la Physique }.
