Original Abstract

Radiation processes play important role in energy balance of thermal plasma in electric arc. Intensive radiation is irradiated from the hot central part of the arc and reabsorbed in cold edge of the plasma. Therefore, besides of continuous and discrete radiation of atoms and atomic ions the influence of molecular species on the absorption properties of the plasma has to be taken into account. Recently, we have studied molecular bands and photodissociation of diatomic molecules. In this paper, attention is given to the photoionization processes. Simple approximate formulas for the calculation of photoionization cross sections are presented; results for molecules O2, N2, NO are compared with experimental and theoretical data from literature.
