Title:

Intensity Ratios of Emission Lines from OV Ions for Temperature and Density Diagnostics

Date of publication:

Mar. 1990

Key words:

OV ion, line emission, intensity ratio, temperature and density diagnostics, excitation rate coefficients, inner sub-shell ionization

Abstract:

Intensity ratios of emission lines from OV ions are calculated for use in temperature and density diagnostics. The dependence on temperature and density of the intensity ratios is shown in graphs. The excitation rate coefficients among n = 2 and N = 3 levels are fitted to an analytical formula and the fitting parameters are tabulated. The rate coefficients are shown graphically.
