The electron impact cross sections like elastic, dissociative ionization, and the total are computed for acetylene from ionization threshold up to 5 keV. The dissociative partial ionization cross sections of various cations are reported using the binary-encounter-Bethe (BEB) model. The elastic cross sections are calculated within molecular framework modified by invoking the single-centre expansion formalism. The total cross sections at these energies are estimated by summing the ionization and elastic cross sections incoherently. The cross sections obtained for different processes are in high degree of convergence with the experimental and theoretical data. The work underlines the role of mass spectrometry data in the study of ionization process as well as the diverse nature of BEB model.
