Implication

Randomized trial investigates charge exchange reactions in molecular nitrogen, indicating pathways and product yields.

Key Points

  • This study aims to investigate charge exchange and dissociative charge exchange reactions between helium ions and molecular nitrogen.
  • Utilized crossed-beam ion velocity map imaging to detect N2+ and N+ yields.
  • Analyzed collision energy range of 1.25–3.96 eV for angular and kinetic energy distributions.
  • Examined the N+ velocity images using Doppler kinematics model.
  • Observed a dominance of resonant processes in CE-yield N2+ across collision energy.
  • Identified three channels in DCE reactions, with distinct products depending on collision energy.
  • Found that the most prominent reaction pathway produced ground-state yields N(4S) + N+(3P).
