THEORETICAL DETERMINATION OF ELECTRON IMPACT IONIZATION CROSS SECTIONS FOR ACETONITRILE (CH3CN) USING THE COMPLEX SPHERICAL POTENTIAL – IONIZATION CONTRIBUTION (CSP-IC METHOD)
Acetonitrile (CH3CN) is a fundamental nitrile compound with immense relevance in astrochemistry, particularly concerning the atmospheric composition of Titan and star-forming regions in the interstellar medium [16, 17]. This paper presents a detailed analytical investigation into the total electron impact ionization cross-section (Qion) for CH3CN. In the present study, the absolute ionization cross-sections are determined rigorously using the Complex Scattering Potential-ionization contribution (CSP-ic) methodology [3, 20]. The calculated Qion values are systematically compared with available experimental data, empirical bond-contribution models, and semi-classical theoretical frameworks such as the Deutsch-Märk (DM) and Binary-Encounter-Bethe (BEB) formalisms [1, 2, 5, 6]. The synthesized data underscores the high efficacy and accuracy of the CSP-ic optical potential model in predicting complex scattering phenomena and isolating the ionization flux across a wide energy spectrum.
