Product energy and angular distributions from the reaction of N + 2 with isotopic hydrogen molecules

Abstract

The energy and angular distributions of N₂H⁺ and N₂D⁺ formed when a beam of N⁺ ₂ passes through a scattering cell containing H₂, D₂, or HD have been measured at relative kinetic energies ranging from 2.3 to 11.6 eV. From some experiments, intensity contour maps that show the complete product velocity vector distribution in the centre of mass system have been generated. Although backward recoil scattering occurs at all energies, most products are scattered forward in the centre of mass system. The shape and position of the forward scattered product peak are largely consistent with the stripping model modified to account for target motion.
