摘要：

The efficiency of the neutralization step in neutralization-reionization mass spectrometry was examined in detail. Collisional charge exchange between a large number of common organic and inorganic cations and He, N2, H2, SF6, CH4, Xe, O2, cyclo-C3H6 and NO revealed that the energy defect for the charge-exchange reaction and the vertical Franck-Condon overlaps of the projectile ion and its neutral counterpart and those of the target species deterimine the efficiency.
