THE MEASUREMENT AND INTERPRETATION OF NeV 2-2 LINE INTENSITY RATIOS

Abstract
A theta-pinch was used to produce NeV 2-2 spectral lines. The intensities of the lines were measured using a grazing incidence spectrometer which had been intensity calibrated by the branching ratios method. The electron temperature and density of the theta-pinch discharge were found by laser scattering. The measured intensity ratios are compared to theoretical predictions based on electron excitation rate coefficients calculated using the R-matrix close coupling method. For two of the measured ratios experiment and theory agree within the experimental uncertainty. For the other two ratios the theoretical prediction is greater than the experimental result.
