Abstract
Recent calculations of Mgviii electron and proton impact excitations rates are used to derive theoretical electron temperature (T e)- and density (N e)-sensitive emission line ratios involving transitions in the 315–782 Å wavelength range. Some of these ratios are presented in the form of ratio–ratio diagrams, which should in principle allow both N e and T e to be deduced. These results are compared with solar observational data from Skylab, but agreement between theory and observation is very poor, probably due to blending.
