CONTRIBUTION OF RADIATION AND COLLISION PROCESSES TO THE DETERMINATION OF ENERGY LEVEL POPULATIONS OF ATOMS IN LOW-TEMPERATURE OPTICALLY THIN PLASMAS

摘要

The zones of energy levels have been described in this paper, as concerns atoms of hydrogen, lithium, sodium, potassium and ceasium; essential within the first group are solely probabilities of radiation transitions, within the second group, these are probabilities of collision transitions, while within the third group, both types of probabilities are comparable. A detailed analysis of targets of this method has been performed herein. Calculations have been performed for all the above mentioned elements within the acting temperatures, under consideration given to the atom of Maxwellian electrons T e = 1000±8000 K, and to the electron density of n e = 10 8 ±10 14 cm -3 .
