Partial double- and single-differential cross-sections for CO2 by electron collision

This Letter reports the partial double-differential cross-section (PDDCS) and the partial single-differential cross-sections (PSDCS) for the CO2 molecule by electron collision at 100 and 500 eV. The two direct ionization channels producing CO2+ and CO22+ and the four dissociative channels producing CO+, C+, O+ and C2+ are examined. The calculations as a function of energy loss were made by employing a semi-empirical formula which requires the oscillator strengths as input data. For the evaluation of PDDCS with respect to exit electron(s) energy and the scattering angle, the differential generalized oscillator strengths were used in the optical limit. The partial ionization cross-sections (PICS) are also calculated, with electron energies varying from ionization threshold to 10 keV.
