Electron impact total (elastic + inelastic) cross sections and total
ionization cross sections are calculated for N2O, CF4, NO
and F2 molecules from the thresholds to 5 keV. A model complex
optical potential is calculated for each collision system from the corresponding
molecular wave function at the Hartree-Fock level. The resulting complex optical
potential, free from any adjustable parameter, is treated exactly in a
variable-phase approach to calculate scattering complex phase shifts and the
total cross sections. The present results are found to be consistent with the
existing experimental measurements.
