We report theoretical and experimental core-level x-ray-photoemission spectra of ${\mathrm{ThCo}}_2$ and ${\mathrm{ThPt}}_3$. Estimates are obtained for the core-hole–5f Coulomb interaction ($U_{\mathrm{fc}}$∼5 eV) and the strength of the 5f–conduction-band hybridization (${\Delta }_{\mathrm{av}\mathrm{\sim }0.1}$ eV). It is found that the shape of the occupied conduction-band density of states influences the shape of the core-level spectrum qualitatively.
