Intensity ratios of forbidden coronal lines of Fe XI at 7892 Å and 3987 Å

The excitation of the lowest (3 s 23 p 4) configuration of Fe XI is discussed and theoretical values for the relative intensities of the Fe XI lines at 7892 Å and 3987 Å are presented. Particular attention has been paid to the quality of the atomic parameters involved and, in spite of probably inacc...

Description
Summary:The excitation of the lowest (3 s 23 p 4) configuration of Fe XI is discussed and theoretical values for the relative intensities of the Fe XI lines at 7892 Å and 3987 Å are presented. Particular attention has been paid to the quality of the atomic parameters involved and, in spite of probably inaccurate rates involving complex configurations (such as 3 p 34 p), it is shown that the predicted intensity ratio obtained is more nearly consistent with available observations that previously published results.
