✦ Synopsis

Electron collision strengths for Mg VI, calculated in the distorted-wave approximation, are presented for all transitions between the 23 levels of the 2s 2 2p 3 , 2s2p 4 , 2p 5 , and 2s 2 2p 2 3s configurations. Radiative data have been calculated utilizing the same four-configuration model of the ion. Proton rates for the transitions between the ground states are also presented. The level balance equations for Mg VI have been solved using these data and comparisons are made with previous results-excellent agreement is found. Theoretical line intensities for the important transitions are presented and compared with lines found in the extreme ultraviolet in a spectrum from the 1989 flight of the Solar EUV Rocket Telescope and Spectrograph. Recent data from the Coronal Diagnostic Spectrometer onboard the Solar and Heliospheric Observatory are also presented.
