Popis: One of the possibilities for creating a population inversion on electronic transitions of molecules involves the use of radiative recombination reactions of halogen atoms. The prospects for this method have been justified theoretically, but there exist no experimental data. The present work was performed in order to obtain recombination radiation of molecular iodine in a high-temperature flow at atmospheric pressure. A single chamber plasmotron was used with a quenching setup and complete spectral and diagnostic apparatus. Pure argon exhibited a transparent flow, with a green luminescence arising upon the introduction of iodine. In the authors' opinion, the spectrum belongs to the system B..-->..X of the I/sub 2/ molecule and has a recombination origin. Three-particle photorecombination apparently predominates with the participation of the argon atom as a third body for stabilizing the quasimolecule. Amplification of the intensity of this radiation in a high-pressure flow requires refining the quenching setup and a more detailed study of the kinetics of the physicochemical and optical processes.
