ABSOLUTE OSCILLATOR-STRENGTHS FOR THE PHOTOABSORPTION (8.5-200 EV) AND THE IONIC PHOTOFRAGMENTATION (11.5-70 EV) OF CF2CL2}, journal = {CHEMICAL PHYSICS}, volume = {151}, number = {3}, year = {1991}, month = {APR 1}, pages = {357-370}, abstract = {Absolute photoabsorption oscillator strengths (cross sections) for CF2Cl2 (freon 12) have been measured using dipole (e, e) spectroscopy in the equivalent photon energy range 8.5-200 eV. The ionic photofragmentation branching ratios and the photoionization efficiency have been determined from time-of-flight mass spectra collected using dipole (e, e + ion) coincidence spectroscopy at equivalent photon energies from the first ionization threshold up to 70 eV. Absolute partial photoionization oscillator strengths for dissociative photoionization of CF2Cl2 have been obtained from the photoabsorption and photoionization data. A dipole induced breakdown scheme for CF2Cl2 under VUV energetic radiation is proposed.}, issn = {0301-0104}, doi = {10.1016/0301-0104(91)80021-9}, author = {ZHANG, WZ and Cooper, G and Ibuki, T and Brion, CE} }
