## תקציר

The rate constants for the reaction of N_{4}^{+} with O_{2}, CO_{2}, H_{2}, and D_{2} have been studied as a function of mean relative kinetic energy in a flow-drift tube using a nitrogen buffer gas. The N_{2}^{+}/N_{4}^{+} equilibrium, which would otherwise deleteriously effect such a study, was suppressed by adding a trace of H_{2} as a purge gas that preferentially reacted with N_{2}^{+}. The reaction rates of N _{4}^{+} with CO_{2} and O_{2} are found to be fast and independent of energy from 0.04 to 0.16 eV. The reactions of N _{4}^{+} with H_{2} and D_{2}, however, have very small rates at room temperature, but the rates increase dramatically with increasing energy, an effect that is attributed to a sensitivity of the reactions to N_{4}^{++} vibrational excitation. The reaction of N_{4}^{+} with H_{2} was studied as a function of temperature and an activation energy obtained. The mobility of N_{4}^{+} in N_{2} was extended to higher E/N values than could be done in earlier studies since the effects of the N _{2}^{+}/N_{4}^{+} equilibrium were suppressed in the present investigation.
