Abstract
The nonequilibrium luminescence of a C2 molecule in a jet of products of the high-temperature erosion of a diaphragm discharge in vacuum (Pinit = 10 Pa) at an early stage of afterglow (0.8–1.2 ms) is studied using the emission spectra of the C2 Swan bands system (d3Пg–a3Пu) 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.
