Electron and ion contributions to the Ne I spectral line broadening

Abstract

On the basis of the experimentally determined 26 prominent neutral neon (Ne I) line shapes (in the 3s-3p, 3s-3p′, 3s′-3p′, 3s′-3p and 3p-3d transitions) we have obtained electron (W e ) and ion (W j ) contributions to the total Stark width (W j ). Stark widths are also calculated using the semiclassical perturbation formalism for electrons and protons as perturbers up to 50 000 K electron temperatures. We made comparison of our measured and calculated W e data and compared both of them with available experimental and theoretical W e values.
