Total Ionization Times in Shock-Heated Noble Gases

Abstract
Total ionization times in shock‐heated argon, krypton, neon, and xenon have been calculated, taking into account atom–atom collisions, electron–atom collisions, and recombination. Excellent agreement is found with the experimental results obtained for argon, neon, and some experiments on xenon. The highly inconsistent results obtained by some investigators for xenon have probably been due to high impurity levels and inadequate testing times in the shock tube.
