Abstract
3pn-3pn-14s,4d and 3pn3d-3pn4p,4f transitions of Fe IX to XVI and Mn VIII to XV are classified through comparison of observed spectra with spectra computed using atomic self consistent field calculations. The required quality of observations was achieved by recording data during the short period when a theta-pinch emitted spectra from the ionization stages under investigation. Accurate wavelength measurements in iron permit correlations to +or-0.02AA with lines in the solar spectrum between 60 and 120 AA. Observations of emission lines from these configurations were previously seriously deficient.Keywords
