Abstract

The trapped-ion measurements of Barlow, Dunn, and Schauer [Phys. Rev. Lett. 52, 902 (1984); 53, 1610 (1984)] on

{CH}_{3}

^{+}

{+ H}_{2}

→

{CH}_{5}

^{+}

+hνare reexamined. It is shown that they require the rate of the stabilizing radiative transition to be 3.5×

10^{4}

s^{- 1}

. This high rate is attributed to an electronic transition involving the state having

{CH}_{4}

{+ H}^{+}

or

{CH}_{3}

+

H_{2}

^{+}

as its dissociation products.
