Study of a heterophase medium based on a relaxing plasma of a diaphragm discharge in vacuum

The nonequilibrium luminescence of a $\rm C_2$ molecule in a jet of products of the high-temperature erosion of a diaphragm discharge in vacuum $(P_{\mathrm{init}} = 10$ Pa$)$ at an early stage of afterglow $(0.8$–$1.2$ ms$)$ is studied using the emission spectra of the $\rm C_2$ Swan bands system $(d^3\Pi_g$–$a^3\Pi_u)$ by comparing the radiation intensities in the bands forming sequences with $\Delta \nu = +1$ 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.
