Electron-impact total ionization cross sections for the CH radical and C{sub 2}H{sub 2} (acetylene) have been calculated using the Binary-Encounter-Bethe (BEB) model. The BEB model combines the Mott cross section and the asymptotic form of the Bethe theory, and has been shown to generate reliable ionization cross sections for a large variety of molecules. The BEB cross sections for CH and C{sub 2}H{sub 2} are in good agreement with the available experimental data from ionization thresholds to hundreds of eV in incident energies.
