X-ray bremsstrahlung isochromat spectra (BIS) as well as photoemission spectra (XPS) are measured for YbP, YbAs and Yb4As3. The BIS spectra have revealed clear differences in the Yb 4f and 5d states between the Yb-monopnictides and Yb4As3. Yb 4p and 5p core XPS spectra have shown the mixed valence of Yb4 As3 compared with the predominance of Yb3+ in Yb-monopnictides.
