Abstract
Microwave afterglow and grating spectrometric apparatus are used to study dissociative recombination in krypton. Over the electron temperature range K and with K, the total rate coefficient may be represented by /sec, with an uncertainty of ± 10%. At thermal energy (300 K) excited states of Kr* having energies up to that of the ion in its ground electronic and vibrational state are observed to result from the dissociative recombination. With microwave heating to K, additional, higher-lying Kr* states (up to ∼ 0.5 eV above the ion ground state) are observed. In both cases the excited states most strongly populated by dissociative recombination appear to be the states.
