Glow discharge excitation and ionization of chromium, comparison with iron

Popis výsledku v původním jazyce

Cr I and Cr II emission spectra from a Grimm-type glow discharge (GD) in argon and neon were analyzed. Intensities of strong resonance Cr I lines were corrected for self-absorption and population functions (experimental Boltzmann plots) of the Cr I system were established. Cr II spectra in both discharges were described by transition rate (TR) diagrams, the contribution of cascade excitation was subtracted and the resulting net-TR diagrams of Cr II were analyzed. The findings were compared with the excitation of Fe I and Fe II systems at similar conditions. A well-known ‘hydrogen effect’, an enhancement of the Cr II line at 267.7165 nm in the presence of hydrogen in a GD plasma, was explained by charge transfer reaction between H+ ions and neutral chromium.n
