Abstract:
Electron scattering is an important means of investigating atomic and molecular structure and plays an important role in many technological applications, from plasma and atmospheric chemistry to material and radiation physics. In this paper, a quantum-mechanical approach to electron molecule scattering across low and intermediate energy regimes is presented. Low-energy electron-molecule interactions were treated using the ab initio R-matrix method, while intermediate-energy scattering calculations were performed using the SCOP and CSP-ic approaches. The systematic calculations performed for diatomic, triatomic molecules, and for polyatomic molecular targets to investigate the dependence of elastic and inelastic scattering processes on incident electron energy and molecular complexity. The results indicate a transition from dominant elastic contributions at low energies to increasing contributions from inelastic processes at intermediate energies, including electronic excitation and ionization. The results obtained by the R-matrix and SCOP/CSP-ic approaches show consistency near the transition between the respective energy regimes, supporting the combined use of these methods for describing electron-molecule scattering across a broad energy range. The study provides a consistent description of electron-molecule scattering across low-and intermediate -energy regimes physically with relevance to applications involving electron collisions in plasma, atmospheric, and radiation related environments.
