NeVII emission lines in the solar EUV spectrum

Recent calculations of electron and proton impact excitation rates in Ne vi i are used to calculate theoretical emission line ratios involving both Del ta n=0 (2-2) and Delta n=1 (2-3) transitions in the similar to 97-895 Angst rom wavelength range. A comparison of these with existing solar observation s, obtained by instruments on rocket flights and on the Skylab mission, rev eals generally good agreement between theory and observation. This provides experimental support for the accuracy of the atomic data adopted in the li ne ratio calculations, and implies that the latter may be applied with conf idence to the analysis of solar and stellar spectra from current and future satellite missions.
