Measurements of Stark widths and shifts of Ne I lines using degenerate four-wave mixing and Thomson scattering methods

摘要: Abstract We report on measurements of Stark widths and shifts four prominent Ne I lines the 3s,3s′-3p transition arrays. The were performed in an atmospheric-pressure arc discharge operated argon–neon gas mixture. Sub-Doppler degenerate four-wave mixing technique was used to measure line profiles, while Thomson scattering yielded plasma parameters: electron density, ne = (0.53–1.33) × 1023 m− 3, temperature, Te = 10,200–20,900 K. measured profiles are symmetric within uncertainty limits. experimental compared with results other experiments theoretical calculations.
