Abstract
Dissociative charge exchange of rare‐gas ions with C2F6 and C3F8 has been studied. The data was obtained with a single‐stage Nuclide mass spectrometer by operating the ion source in the Čermák—Herman mode. A charge‐transfer mass spectrum was obtained for C2F6 and C3F8 with each rare‐gas ion except Xe. The relative ionic abundances were interpreted as portraying the dissociation of C2F6+ and C3F8+ as a function of their excitation energy. The normalized abundance of CF8+ as a funetion of excitation energy shows two maxima which indicates that two processes contribute to CF3+ formation from C2F6 and C3F8.Keywords
