Recent R-matrix calculations of electron excitation rates for transitions in Mg XI are used to determine the theoretical emission-line ratios as a function of electron temperature. These are found to be more temperature sensitive than the normal diagnostic for He-like ions, by factors of approximately 2.6 and 5.9 respectively, between Te = 1 × 106 K and 1 × 1O7 K. Electron temperatures deduced from R1, and R2 ratios observed by the P78-1 satellite for solar flares and active regions are in excellent agreement with those previously determined by other methods.
