Abstracts

EN

Charge-exchange ion-molecule reactions of Ar^+ ions with CF_4 have been studied in the pressure range 1.33-39.99 Pa. A quadrupole mass spectrometer with a high-pressure ion source has been used for measuring gaseous ion-molecule reactions in the mixture of 1% CF_4 and 99% Ar. The fractional abundance I_i/∑ I_i of the observed CF_3^+, CF_2^+ and argon ions has been determined as a function of the gas mixture pressure (at the values of the repeller electrode potentials V_{R} ranging from 2 to 10 V).
