Abstract
Electronic excitation spectra and absolute oscillator strengths (cross sections) have been measured in the vacuum ultraviolet and soft X-ray regions for the valence- and inner-shell (Cl 2p, 2s; C 1s) photoabsorption of CCl 4 from 5.5 to 400 eV, using low-resolution (1 eV fwhm) dipole (e, e) spectroscopy. High-resolution (0.048 eV fwhm) dipole (e, e) spectroscopy has been used to study the valence region from 5.0 to 30 eV in greater detail. These data are compared with previously reported optical measurements in those limited energy regions where such data exist. Dipole (e, e+ion) spectroscopy has been used at a resolution of 1 eV fwhm to measure the photoionization efficiency and ionic photofragmentation branching ratios for CCl 4 from 11.0 to 80.0 eV in the valence-shell region and from 190.5 to 220.5 eV in the vicinity of the Cl 2p inner-shell edge. Absolute partial oscillator strenghts for dissociative photoionization channels of CCl 4 have been derived. Using these and other spectroscopic data, a dipole-induced breakdown scheme for CCl 4 in both the valence-shell and Cl 2p inner-shell regions is proposed.
