Abstract

In the present work the opportunity of use of the emission with λ ∼ 329 nm in Ar-Xe mixtures in radioisotope light sources is investigated. At excitation of this mixture by α-particles the transitions from a state Ar+(2P1/2)Xe (λ∼329 nm and ∼508 nm) are observed only and there are no transitions from Ar+( 2P3/2)Xe. Intensity (in photon/s) of 508 nm band is approximately in 17 times less than intensity of 329 nm band. Efficiency of a luminescence, the attitude of power of the emission in a band of 329 nm to the power enclosed in gas, makes about 5 %. At use of α-sources helium collects, dependence of intensity of emission in a band of 329 nm from the pressure of helium in a mixture Ar-Xe-He is investigated. Rate coefficients of some two- and three-body reactions have been measured or estimated from experimental relations.
