Ne II Stark Width and Shift Regularities

Stark widths of 48 and Stark shifts of 36 Ne ii spectral lines have been measured in a low-pressure pulsed arc plasma. Of these, 21 widths and 25 shifts have not been previously reported. This has allowed us to analyze Stark width and shift regularities in some multiplets and transition arrays of th...

Description
Summary:Stark widths of 48 and Stark shifts of 36 Ne ii spectral lines have been measured in a low-pressure pulsed arc plasma. Of these, 21 widths and 25 shifts have not been previously reported. This has allowed us to analyze Stark width and shift regularities in some multiplets and transition arrays of this species. The electron density and temperature in this experiment were in the range 1.12-[image] m super(-3) and 25,000-45,000 K, respectively. The results have been compared to data from previous experimental work, as well as to theoretical models. Stark parameter regularities experimentally determined in this work provide a basis for estimating the Stark parameters for Ne ii lines that have not yet been observed.
