Interpretation of unresolved transition arrays in the soft-x-ray spectra of highly ionized molybdenum and palladium

Abstract
Previously published theoretical formulas for the mean wavelengths and spectral widths of unresolved transition arrays are applied to transitions of the types 3dN+13dN4p and 3dN+13dN4f observed in highly ionized spectra of Mo and Pd. Agreement with experiment is excellent and opens the way to the quantitative interpretation of the intensities.
