“…Many investigations have studied the collision processes in afterglow plasmas [1][2][3]. Analysis of the processes in rare-gas positive-column plasmas, in which atomic ions, molecular ions and metastable atoms participate, has also been carried out in detail [4][5][6][7]. The self-absorption method [8] and its modification [9] is very efficient for measuring the metastable concentration in gases.…”

Contributions of krypton ions and krypton metastables, as well as contributions of gamma-radiation and cosmic rays to the electrical breakdown in a krypton-filled tube have been analysed by use of the time delay method. The experimental results have shown that each of these contributions strictly depends on the afterglow period. The time delay method has enabled the determination of both the recombination time of positive ions and the lifetime of metastables, created in previous discharge. The obtained value of metastable lifetime is in agreement with its theoretical value. The dependence of the electrical breakdown on exposed dose rate of gamma-rays from the radiation source has also been investigated.

“…Much work has been done to study the collision processes and the chemical reactions of ions with excited atoms by measuring the decay of metastables in afterglow plasmas (Phelps and Molnar 1953, Phelps 1955, Phelps and Pack 1955. Some work has also been done to study positive column plasmas, including the effect of metastable atoms (Schlie and Verdeyen 1969, Rajotte 1973, Dyatlov et al 1975. We report here another measurement of metastable atom density in helium and neon gas positive column plasmas over a wide range of discharge conditions using an improved self-absorption method.…”

An improved self-absorption method obtained from the parallel-beam modification of Harrison's method for measuring the metastable atom density in gas discharges has been proposed. This method has the advantage of high spatial resolution in measurement with a relatively simple apparatus. The metastable atom densities of He (21S0 and 23S1) and Ne (1s3 and 1s5) in the positive column plasmas have been measured using this improved self-absorption method by varying the gas pressure from 1 to 10 Torr and the discharge current from 10 to 50 mA. 'Constriction' of the radial metastable atom density distribution in neon plasma has been observed. All experimental results are given and discussed.
