COLLISIONAL-RADIATIVE RECOMBINATION OF IONS AND ELECTRONS IN HIGH-PRESSURE PLASMAS IN WHICH ELECTRON TEMPERATURE EXCEEDS GAS TEMPERATURE

The recombination rate of electrons in a hypothetical helium-like plasma at high pressure is calculated for cases in which the gas temperature is fixed at 300°K, and the electron temperature is varied from 300 to 2000°K. Neutral collision-induced recombination and electron collision-induced recombination are considered for ranges of electron density from 108 to 1013 cm-3 and gas densities from 1016 to 1019 cm-3. An inverse three-halves dependence of recombination coefficient on electron temperature is found for certain densities. © 1969 The American Physical Society.
