โœฆ Synopsis

The recent twelve-state R-matrix calculations of electron excitation rates in CIII by Berrington are used to derive level populations applicable to the solar transition region. Line ratios R = I(2p 23pc _ 2s2p 3po)/i(2s2p lpo _ 2s 2 Iae ) and R 2 = I(2p 2 l se --2s2p lpO)/l(2p23pc _ 2s2p 3po)deduced from these data in conjunction with the relevent transition probabilities are found to be in much better agreement with the observed quiet Sun values than those determined from the level population calculations of Keenan et aL

The electron collision excitation rates recently calculated for transitions in Si xIII by Keenan et al. (1987) are used to derive the electron temperature sensitive ratio G( = (f + i)/r) and the density sensitive ratio R(=f/i), where i,f, and r are the intercombination (ls 2 1S -ls2p 3P1, 2) forbidd
