Abstract

The results are presented of a study of the forward and reverse rate coefficients (

k_{f}

and

k_{r}

) at thermal energies for the reaction

{Ar}^{+} ({}^{2}P_{\frac{3}{2}}) + N_{2} \underset{k_{r}}{\overset{k_{f}}{⇄}} Ar + {N_{2}}^{+} (ν = 0, 1)

. The data were obtained in a selected ion flow tube. It is shown that at 300 K the forward reaction proceeds predominantly via the

{N_{2}}^{+} (ν = 1)

product channel and at 80 K via the

{N_{2}}^{+} (ν = 0)

channel.

k_{r}

is large for

{N_{2}}^{+} (ν = 1)

which probably explains the anomalies in previous studies of

k_{f}

in afterglows in which Ar and

N_{2}

coexisted.
