摘要：

The ionization efficiencies of fast beams of CO and C2H4, with oxygen as target gas were shown to increase with increasing translational energy and to decrease with increase in internal energy. The latter may arise from a greater probability of homolysis in the neutral projectile species; it is not likely to arise from increased ionization of the target. Experimental parameters (and their validity) relating to the measurement of collision-induced dissociative ionization mass spectra and which are also applicable to the reionization step in neutralization-reionization mass spectra were investigated.
