Study of a Heterophase Medium Based on a Relaxing Plasma of a Diaphragm Discharge in Vacuum

The nonequilibrium luminescence of a C 2 molecule in a jet of products of the high-temperature erosion of a diaphragm discharge in vacuum ( P init = 10 Pa) at an early stage of afterglow (0.8–1.2 ms) is studied using the emission spectra of the C 2 Swan bands system ( d 3 П g – a 3 П u ) by comparing the radiation intensities in the bands forming sequences with ∆ν = +1 and 0. The experimental results at the stage of the end of condensation of discharge products are obtained. The processes of obtaining a variety of highly dispersed structures are considered and their parameters are evaluated.
