The investigation of electric and optical characteristics of negative coronar discharge (CD), received in electrode systems ‟needles–grid" was carried out. The coronar discharde was firing in the Helium and mixtures He/$R$, He/Ar(Kr)/$R$, where ($R$ — Ne, Ar, Kr, Xe) was under the pressure of 50… 350~kPa and mixture compositions typical for the lasers of high pressure on rare gases.

The bipolar CD in the given gas media can be used in the systems of UV–lasers preionisation on $p$–$s$ and $d$–$p$ transitions of Ar, Kr, Xe atoms and lasers on the transitions Ne(3$p$–3$s$). In Helium and mixtures He/$R$ in an outward zone bipolar CD, a stable discharge with a rather high spase homogenity was received. The volt–amper characteristics, the spectral radiation and the dependence of radioation intensivity of lines of rare gases atoms on the discharge parameter. The fundamental process of population and depopulation $p$–$s$ state atoms of rare gases in the given plasma has been suggested in this article.
