Abstract

We report total cross sections for electron collision with O2 and S2 molecules in the energy range 0.1–2000eV by combining two theoretical methods. Below the ionization threshold of the target, total cross section is calculated by the ab initio R-matrix method through Quantemol-N software. For intermediate and high energies, we have applied a Spherical complex optical potential formalism. Comparison is made with the available theoretical and experimental data and a reasonable agreement is observed. The high energy cross section for S2 molecule is reported for the first time.
