Dissociative recombination at elevated temperatures. II. Comparison between theory and experiment in neon and argon afterglows

For pt. I see ibid., vol. 5, 1773, (1972). The ground vibrational state model of the dissociative recombination is extended slightly and applied quantitatively to experiments on the temperature dependence of recombination in Ar 2 + and Ne 2 + . It is found that the experimental results can be fitted fairly accurately with the lowest vibrational state for argon and that the first excited state is needed for neon. Improved predictions are made for the vibrational spacing of these rare gas ions, which new information deduced about the final state potential curves. In general, the agreement tends to confirm earlier arguments about the relative slowness of recombination from vibrationally excited states.
