The electron-impact ionization of NF{sub 3} has been studied using two different experimental methods, the fast-beam technique at City College and a high-resolution double-focusing mass spectrometer at Greifswald. Absolute parent ionization cross sections were measured independently by both groups and the results were found to agree to within 20% (at 70 eV). The authors also report measurements of the partial cross sections for dissociative ionization of NF{sub 3} carried out in both apparati. Ionization and dissociative ionization cross sections for the NF{sub 2} and NF free radicals could only be measured using the fast-beam technique by the City College group. The measured cross sections will also be compared to calculated total single ionization cross sections for NF{sub 3}, NF{sub 2} and NF using a new additivity rule.
