A Theoretical Study of Scattering of Electrons and Positrons by CO₂ Molecule

This article presents a theoretical investigation of the differential, integrated, elastic, inelastic, total, momentum-transfer, and viscosity cross-sections, along with the total ionization cross-section, for elastically scattered electrons and positrons from a carbon dioxide (CO${}_2$) molecule in the incident energy range of 1 eV $\le E_i\le$ 1 MeV. In addition, for the first time, we report the spin polarization of e${}^{\pm }-$CO${}_2$ scattering systems. The independent atom model (IAM) with screening correction (IAMS) using a complex optical potential was employed to solve the Dirac relativistic equation in partial-wave analysis. The comparison of our results with the available experimental data and other theoretical predictions shows a reasonable agreement in the intermediate- and high-energy regions.
