Elastic scattering of low-energy electrons by carbon disulphide

We report results from an ab initio calculation of low-energy electron scattering by CS2 molecules using the Schwinger multichannel method with pseudopotentials. We calculated elastic integral, differential and momentum transfer cross sections in an energy range from 5 eV up to 50 eV and compared our results with available theoretical results and experimental data. Through the symmetry decomposition of our integral cross section and eigenphase sum analysis, wt: found cross section peaks that may be interpreted as broad shape resonances in the cases of the Sigma(g) Pi(g), Pi(u), and Delta(u) symmetries. Among these possible resonances, the Pi(g), Pi(u), and Delta(u), are being reported for the first time.
