Dissociative Electron Attachment to Polyatomic Molecules - III : Ammonia

TL;DR

This study investigates how electrons attach and cause dissociation in ammonia molecules, analyzing fragment distributions at specific resonances to understand the underlying molecular dynamics.

Contribution

It provides detailed kinetic and angular distribution data for ammonia's dissociative electron attachment at known resonances, highlighting deviations from simple recoil models.

Findings

Angular distributions deviate from axial recoil approximation

Fragment kinetic energies measured at two resonances

Comparison with water shows similar deviations

Abstract

In this paper, we discuss the dissociative electron attachment process in Ammonia. Kinetic energy and angular distributions of H^{-} and NH_{2}^{-} fragment anions across the two well known resonances at 5.5 eV and 10.5 eV are reported. The angular distributions show deviation of axial recoil approximation akin to that observed in water.
