Low-Pressure Barrier Discharge as a Source of Radiation for Spectroscopic Study of Collisional-Radiative Recombination of Doubly Charged Ions

In this paper, we describe the first results of the experiment, which made it possible to compare directly the rates of collisional-radiative recombination of Ne+ and Ne++ ions with electrons in plasma. As the main result of the work, we present the ratio of the coefficients of collisional-radiative recombination of doubly and singly charged neon ions, which is several times higher than the value predicted by the theory of the process in a purely collisional model.
