Using synchrotron radiation as a continuum light source, dissociative photoionization of CF4 has been studied in the photon-energy region of 23-120 eV. Ion branching ratios were obtained by analyzing time-of-flight mass spectra and were converted to the absolute partial cross sections for the production of singly charged CF3+, CF2+, CF+, F+, and C+ ions, as well as doubly charged CF32+ and CF22+ ions by using the reported total absorption cross sections of CF4. Ion branching ratios were differentiated with respect to the incident photon energy. The results obtained by this analytical photoion spectroscopy clearly show dissociation pathways of the CF4+ and CF42+ ions, many of which are observed for the first time in the present study. These pathways are discussed by comparing with the reported electronic states of the ions.
