Electromagnetic radiation absorption and reaction rates in partially ionized plasma

The balance equations of particle number and momentum for systems with ionization and recombination of particles have been obtained. In the limit of low temperatures, for a hydrogen-like four-component system in an ionizing radiation field the dispersion relations have been found, which prove the existence of electromagnetic radiation absorption regions whose boundaries depend on the degree of ionization and elementary processes rates. Experimental determination of these boundaries may provide data on elementary processes rates.
