Spectroscopic study of a glow discharge in krypton

The concentrations of excited atoms at the 4p⁵5s and 4p⁵5p levels of Kr I are determined by the reabsorption and emission methods. The absolute values off for ten Kr I lines in the infrared region of the spectrum are determined from the known value off₈₈₁₂ and from measured relative values of the oscillator strengths. Processes leading to the formation and decay of excited states of krypton atoms are discussed.In conclusion, the authors wish to thank Professor A. N. Tekuchev for valuable comments, and also Yu. P. Grigorov, T. F. Dubtsov, L. V. Zaitsev, and V. S. Korchunov for assisting with the experiments.
