Abstract

Visible afterglow radiations from low‐pressure weakly ionized inert gases are partially quenched during irradiation of the gases by the infrared produced with CO₂ lasers (photon energies ∼ 0.1 eV). The most plausible interpretation of the effect appears to involve photoionization or photoexcitation of neutral atoms in excited states populated during the process of recombination.
