COMPARISON OF SATELLITE SPECTRA FOR H-LIKE Fe AND He-LIKE Fe, Ca, AND S CALCULATED BY THREE DIFFERENT METHODS

Abstract Theoretical atomic data from the MZ code with the Z expansion method by Safronova, the AUTOLSJ code using a statistical model potential by Cornille, and the YODA code derived from the MCDF approximation by Nilsen for the wavelengths and intensities of the dielectronic and inner shell satellite lines of He- to C-like Fe and Li-like Ca and S ions are compared in the form of synthetic spectra. The agreement is rather good, being within 20% for the main satellite lines. As an example of the application of the data we analyze the spectrum of Fe XXV from a solar flare obtained by the Yohkoh space vehicle.
