Abstract

A microwave-afterglow mass-spectrometer apparatus has been used to determine the dependence on electron temperature

T_{e}

of the recombination coefficient of electrons with the dimer ion

N_{2}^{+}

·

N_{2}

. We find

α = (1.4 \pm 0.2) \times 10^{- 6} {[T_{e} \frac{(K)}{300}]}^{- 0.41}

{cm}^{3}

/s over the range

300 \leq T_{e} \leq 5600

K, and

T_{+} = T_{n} = 300

K. These results are quite similar to those found for the C

O^{+}

·CO dimer ion but quite different from the

T^{- 1}

dependence inferred from previous measurements in nitrogen in which the ions were not mass identified.
