Systematic Structure in theK-Edge Photoabsorption Spectra of the4dTransition Metals: Theory

The $K$-edge photoabsorption spectra of the $4d$ metals calculated by the linear augmented-plane-wave method yield good agreement with the measured data. The prominent systematic features of the spectra, most easily discussed in terms of the $l=1\mathrm{}$ projected density of final states, are simply related to the underlying band structure. The results for Zr, Mo, Pd, and Ag are presented here.
