✦ Synopsis

Equilibrium population of Fextv levels in coronal conditions was calculated including configurations 3sZ3p, 3s3p ~, 3s23d, 3p 3, 3s3p3d, 3s~4s, 3s24p, 3s24d, 3s~4f Relative populations of selected levels are given in Table VII. Figure 1 shows the dependence of relative intensities of the strongest lines on electron density. Certain line ratios can be used for the determination of Ne. E.g., at T= 2 • 106 K and with a dilution factor 0.4, the intensity ratio of 2211.3 and 2219.0 changes by a factor of 65 if No increases from 107 to 101I (Table VIII). Cascades from the 3s3p3d and 3p~ configurations are important in the population of some levels of 3s3p 2 (Table VI). A possibility of identification of additional lines in the solar spectrum is indicated.

The relative intensity of two CI lines at 1993.6 • and 1657.4 A, observed in the limb spectrum of the sun, is a factor 2.6 • 10 a larger than that expected if both lines were optically thin. It is shown that the observed intensity ratio may be explained in terms of the transfer of photons from 2 165
