Spectral line intensities calculations for Ne-like argon plasma

摘要

Energy level populations and spectral line intensities in plasmas are studied using an advanced uniform approach for the calculation of ion energy levels and elementary processes rate coefficients in plasmas. The spectrum of Ne-like argon for the uniform steady-state plasma is calculated for a wide variation of electron temperature and density. Hence the most efficient lasing at 5 3p - 3s transitions with wavelengths 697.6, 860.6, 727.5, 725.7, 670.7 angstroms should be expected at 10$+19$/ $LS n$-e$/ $LS 10$+20$/ cm$+$MIN@3$/ and T$-e$/ approximately 60 eV. It is shown that at electron densities of 10$+15$/ $LS n$-e$/ $LS 10$+21$/ cm$+$MIN@3$/ ratios of the strongest 3p - 3s line intensities are sensitive to electron density; their dependence on electron temperature is much less pronounced.
