摘要：

Guided ion beam mass spectrometry studies designed to measure the appearance energy for CF+3 from CF4 are reported. In contrast to a previous observation, we find that there is no flouride transfer equilibrium between CF+3. Rather, the thresholds for formation of CF+3 from reaction of ground state Kr+ (2P 3 2) with CF4 and from collision-induced dissociation of CF+3 by Xe are used to establish AE(CF+3/CF4).Both results are in good agreement although the former experiment yields a more precise value, namely 14.24 ± 0.07 eV. © 1990.
