✦ Synopsis

The recent level population calculations for Ne v by Aggarwal are used to determine the theoretical emission line ratios RI = l(2s2p 3 ID~ -2s22p 2 lDe)/I(2s2p3 3D~ -2sZ2p ~ 3p~) and Rz = i(2s2p3 1DO _ 2sZ2pZ lDe)/l(2s2p3 3DO _ 2s~2p2 3p~). A comparison of these with observational data for a solar flare and erupting prominence obtained with the NRL XUV spectrograph on board Skylab reveals that Rt and R 2 are in their predicted high density limits. Although the ratios cannot be used as density diagnostics for values of n e typical of the solar transition region, it is shown that they are temperature sensitive and hence may be employed to determine the electron temperatures of Ne v line emitting regions.
