X-ray absorption spectroscopy is used to investigate the near-L-edge structures of Pd in pure Pd and bulk ${\mathrm{Pd}}_{2}$Si and PdSi silicides. Possible many-body effects are suggested to explain the apparent discrepancy between the occurrence of ${L}_{2}$,3 white lines and the 4d hole filling in Pd silicides. The interpretations of the extended fine structures and of the near-edge features are correlated with each other in order to find common support for a dynamical relaxation model for the ${L}_{2}$,3 deep core holes of Pd silicides.
