Emission of FeXV in coronal conditions

Relative intensities of 12 spectral lines of Fexv were calculated for various values of N _e and T _e. Nine levels of the ion were taken into account and all excitation and de-excitation processes were considered. The results are represented in Figures 2a, b, c.Research associate at J.I.L.A. for the year 1965–66.Visiting fellow of J.I.L.A. for the year 1965–66.
