Abstract

The vibrational temperature,

T_{v}

, of

N_{2}^{+}

and

O_{2}^{+}

ions drifting in a helium buffer has been determined for the first time quantitatively as a function of

\frac{E}{N}

. For both ions

T_{v}

reaches ∼ 3000 K at

\frac{E}{N} ≃ 150 \times 10^{17}

. This result resolves various previously inexplicable aspects of the behavior of ion-neutral reactions as a function of energy.
