Abstract
A careful search has been made for the ion pair process CF4 + e → CF3+ + F− + e in the electron bombardment of CF4 using a coincidence mass spectrometer with near monochromatic electrons. A weak but easily detectable ion pair process was observed with a threshold in the neighborhood of 12 eV. In addition, a low level of CF3+ ions was observed below the ionization potential of CF3. This was attributed to the ionization of excited CF3 radicals.Keywords
