“…Thermal neutron flux density at stationary nuclear reactor reaches 10 13 to 10 14 n/cm 2 s, and gas mixtures' pumping power does not exceed a few W/cm 3 . Therefore, research on stationary reactors (IRT-2000 in Moscow Engineering Physics Institute (MEPhI), our works on WWR-K reactor) was mainly associated with the study of the spectral characteristics of plasma [50,51], as well as the development of lasers with non-self-maintained discharge (WWR-K reactor) [52].…”

We briefly describe the basic processes of formation and relaxation of nuclear-induced plasmas of gas mixtures, especially the processes of inverse population creation in nuclear-pumped lasers (NPL). A review of the work to create and research nuclearpumped lasers is in progress: on transitions of atoms and atomic ions and on molecular transitions. An increased focus is on the gas media, which we also study on WWR-K nuclear reactor and DC-60 ion accelerator. The studies on emission of heteronuclear ionic molecules of inert gases are also reviewed.

“…The activity of the α sources was 9.6 GBq, which corresponds to an average energy deposition under 2 atm of helium of W ≈ 3 × 10 −5 Wcm −3 and a mean ionization rate according to gas volume of S ≈ 4 × 10 12 cm −3 s −1 . The apparatus for study of luminescence spectra of gas mixtures in the active zone of a nuclear reactor is described in Khasenov (2004;2014).…”

The mechanisms of level population in high pressure gas lasers pumped by ionizing radiation at the 3p-3s transitions of neon, the d-p transitions of argon, krypton, xenon, and triplet lines of mercury are analyzed. It is shown that dissociative recombination of molecular ions with electrons is not the basic process responsible for populating the p levels of inert gas atoms. It is assumed that the most likely channel for d-level population is direct excitation of atoms by secondary electrons and excitation transfer from buffer gas atoms, with p levels being populated by transitions from upper levels. Dissociative recombination of mercury molecular ions with electrons is the basic process responsible for populating the 7 3 S 1 level of mercury atoms.
