Abstract

In this paper we report calculations of various total cross sections namely total elastic (Qel), total ionization (Qion), total (complete) cross sections (QT) and grand total cross sections (QTOT) for the impact of electrons on methyl compounds namely, methanol, methylamine and total ionization cross sections on reactive diatomic radical SO and SO2 molecule at energies from circa threshold to 2000 eV. We have employed the 'Spherical Complex Optical Potential' (SCOP) formalism to evaluate Qel, Qinel, QT and QTOT and used our semi-empirical, 'Complex Spherical Potential — ionization contribution' (CSP-ic) method to derive Qion. These results are compared with available experimental and other theoretical data and overall good agreement is observed
