The one-particle Green's function method in the Dirac-Hartree-Fock framework. I. Second-order valence ionization energies of Ne through Xe Dissociative electron attachment near threshold, thermal attachment rates, and vertical attachment energies of chloroalkanesThe relaxation of a nonequilibrium distribution of electrons in a mixture of CCl 4 with either Ar or Ne is studied. In this paper, electron-CCl 4 and electron-inert gas elastic collisions, vibrationally inelastic collisions between electrons and CCl 4 , as well as the electron attachment reaction with CCl 4 , are included in the analysis. The time dependent electron energy distribution function is determined from the Boltzmann equation and the energy relaxation times are determined. The coupling of the thermalization process and the attachment process are discussed in detail. The results from the calculations are analyzed analogous to experimental studies, and the methodology of the experimental reduction of the data is studied.
