The discrete structures in the valence region and in the vicinity of the phosphorus 2p and chlorine 2p inner shells have also been studied at higher resolution (0.05-0.1 eV fwhm). Evaluation of the S(-2) sum using the presently reported absolute photoabsorption oscillator strength data gives a dipole polarizability for PCl3 within 1\% of the experimental value. The photoionization efficiency, ionic photofragmentation branching ratios, and absolute partial oscillator strengths for molecular and dissociative photoionization have also been determined for PCl3 by dipole (e,e + ion) coincidence spectroscopy from the first ionization threshold up to the chlorine 2s edge.}, issn = {0301-0104}, doi = {10.1016/S0301-0104(97)00048-7}, author = {Au, JW and Brion, CE} }
