Abstract Secondary electron energy dependent ionization cross-sections for the C2H2 and C2H5OH molecules by electron-collision have been calculated at a set of impinging electron energies 100 and 200 eV. The revisited Jain-Khare semiempirical approach based on the Born approximation has been employed to calculate these cross-sections. The averaged secondary electron energy and the integral total ionization cross-sections are evaluated from the energy dependent ionization cross-sections in energy range ionization threshold to 2000 eV. The calculated total ionization cross-sections are extended up to 6000 eV using Born-Bethe analysis. A comparison of the presently evaluated total ionization cross-sections with the available various theoretical and the experimental results revealed a satisfactory agreement.
