High-resolution photoabsorption spectra of Ba 4d4f in the solids of barium compounds of BaO, BaS, BaF2, BaCl2, BaI2, and BaCO3 have been measured by using synchrotron radiation. The two distinguished photoabsorption lines observed in this work in the energy range of 9297eV are identified to be atomlike spectra of barium arising, respectively, from the transitions of 4d101S0 to 4d94f13P1 and 4d94f13D1. The line shapes and the peak energies of the photoabsorption lines from 4d101S0→4d94f13D1 of these compounds have been determined by a curve-fit analysis. Below the resonance peak, some satellites are found in the solids of BaF2, and BaCl2. No such satellites can be identified in the other solids. The variation of the peak energies of the halides can be attributed mostly to the variation of the coordination charge of Ba ions as calculated by a simple formula, but it is not so for the oxides.
