Study of processes of nuclear reaction energy conversion into energy of optical radiation

Abstract

This paper presents the preliminary results of the reactor experiments to study the spectral-luminescent properties of gaseous mixtures (based on He, Ne and Kr noble gases). The investigated gaseous mixtures were excited by the products of 6Li(n,α)3H nuclear reaction. The IVG.1M research reactor acted as a source of thermal neutrons. The description of experimental facility and experimental ampoule device for reactor irradiation is presented. The highest intensity of radiation was observed in experiments with He-Ne gaseous mixture on lines with a wavelength of 585.2 nm, 640.4 nm and 703.4 nm. He-Ne mixture’s main energy in the range of 500 nm to 800 nm was radiated on atomic transitions 3p-3s of neon. The most intensive transitions in neon were 3p’[1/2]0 - 3s’[1/2]10 with λ = 585 nm and 3p[1/2]1 - 3s’[1/2]20 and 3s[3/2]10 with λ = 703.4 nm and 724 nm.
