Nature of deviations from the regularities of three-particle recombination in dense plasma
An explanation is proposed for the phenomenon of deviations from the functional laws of three-particle recombination in dense electric arc plasma of argon at an initial electron density of ∼ 10¹⁶ cm⁻³. Experimental data, which are the basis of the work, were obtained by spectral and probe methods du...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Резюме: | An explanation is proposed for the phenomenon of deviations from the functional laws of three-particle recombination in dense electric arc plasma of argon at an initial electron density of ∼ 10¹⁶ cm⁻³. Experimental data, which are the basis of the work, were obtained by spectral and probe methods during the study of plasma decay of a micro-second pulse electric arc in argon 6 μs at an initial pressure of 70…700 Pa and a discharge current amplitude of 6 kA. Theoretical estimates show that the reason of the observed effects is the self-absorption of resonant spectral lines of argon, which significantly limits the recombination flow of electrons in the energy structure of atoms. |
