Abstract

In this paper, we discuss the dissociative electron attachment process in Methane. Kinetic energy and angular distributions of H^- and CH₂^- fragment anions across the broad resonance about 10 eV is reported. Angular distribution of H^- ions changes from being perpendicular to forward-backward scattering across the resonance. Possibility of Jahn-Teller effect on excitation of the triply degenerate 1t2 molecular orbital is inferred.
