Determination of angular cross sections for electron dissociative ionization of the CCl4 molecule

Abstract

Secondary electron energy and angle dependent differential cross sections for the product ions CCl3+, CCl2+, CCl+, C+, Cl+, Cl2+ and CCl3++ resulting from the dissociative ionization of CCl4 by electron collision have been calculated at fixed incident electron energy of 100 eV. The Jain-Khare semiempirical formulation that requires the oscillator strength data as input has been employed. The corresponding partial and total integral ionization cross sections have also been evaluated in the energy range varying from the ionization threshold up to 1000 eV. The partial and the total ionization cross sections are compared with the previously reported experimental and theoretical results leading to a reasonably good agreement.
