The Influence of the Electron κ-Distribution in the Solar Corona on the Fe <Emphasis Type="SmallCaps">VIII</Emphasis> Fe <Emphasis Type="SmallCaps">XV</Emphasis> Line Intensities
Changes in the excitation equilibrium of Feviii Fe xv in the solar corona due to the electron non-thermal κ-distribution are studied. The shape of the distribution affects the electron excitation rate and thus the relative intensities of the spectral lines. Since the shape of the electron distribution function influences also the ionization equilibrium of Fe, both effects change the final intensities of the lines. Possibilities for diagnostics of the shape of the electron distribution in the solar corona are discussed. Synthetic spectrum of Fe for T = 1.58× 106 K and n e = 108 cm-3 is shown together with the synthetic spectra computed with DEM for the quiet Sun.
