Abstract:The luminescence of XeF*(B 2II1/2) molecules from a zone formed in the injection of SF6 gas into a freely flowing xenon plasma jet is investigated. The experiments show that both the energy characteristics of the luminescence and the geometrical dimensions of the plasmachemical reaction zone can be controlled by varying the power input to the plasmatron and the mass flow rates of SF6 and the xenon plasma. It is shown that the main contribution to the production of XeF*(B 2II1/2) excimer molecules under the given experimental conditions is from two-particle ion-ion reactions involving Xe ions and SF 6 − and SF 5 − molecular ions.
