Mobilities and Reaction Rates of Neon Ions in Neon

The mobilities of

{Ne}^{+}

and

{Ne}_{2}^{+}

ions in neon have been measured at 300°K. The mobilities of

{Ne}^{+}

and

{Ne}_{2}^{+}

at low

\frac{E}{p_{0}}

are given by the equations

K ({Ne}^{+}) = 4.07 {[1 + 8.0 \times 10^{3} {(\frac{E}{p_{0}})}^{2} + 2.0 \times 10^{- 6} {(\frac{E}{p_{0}})}^{4}]}^{- \frac{1}{8}}

and

K ({Ne}_{2}^{+}) = 6.14 {\frac{[1 + 8.3 \times 10^{- 3} {(\frac{E}{p_{0}})}^{2}]}{[1 + 2.0 \times 10^{- 3} {(\frac{E}{p_{0}})}^{2} + 8.4 \times 10^{- 6} {(\frac{E}{p_{0}})}^{4}]}}^{\frac{1}{4}}

, with

\frac{E}{p_{0}}

in V/cm Torr. The

{Ne}^{+}

was observed to convert to

{Ne}_{2}^{+}

by a three-body reaction with a rate coefficient ranging from about 7×

10^{- 32}

{cm}^{6}

/sec at

\frac{E}{p_{0}} = 2.0

V/cm Torr to about 5×

10^{- 32}

{cm}^{6}

/sec at

\frac{E}{p_{0}} = 6.0

V/cm Torr.
