Abstract:
This paper presents a comparative quantum mechanical study of the electron molecule scattering at low-to-high-energy regimes, covering incident electron energies from sub electronvolt to kiloelectron volt levels. Representative diatomic, triatomic, and polyatomic molecules were chosen to study the influence of molecular complexity on the dynamics of scattering. The elastic and inelastic processes and resonance processes were calculated with ab initio R-matrix calculations to provide low-energy processes, and the high-energy processes were calculated with complex optical potential-based methods that take into consideration the ionization and absorption processes. It has been found that there is a pronounced shift between predominantly elastic scattering at low energies to ionization processes at high energies, with polyatomic molecules having the largest inelastic and ionization cross sections among the simple species. Systematic cross-sectional energy-dependent analyses revealed the same trends across all molecular targets and the integrated methodology was compared to both the experimental and theoretical standards. This paper offers a coherent model of electron scattering across a broad spectrum of energies, with application in the atmospheric, biological, industrial and fundamental studies of molecules.
