RIXS spectra of ytterbium in YbInCu4. The incident energy was scanned in the region of the Yb2+ signal (thick part of absorption curve in the inset). At its resonance the divalent peak is the most prominent spectral feature below TV (T = 15 K). Above TV (T  =  295 K) the Yb valence is closer to 3 and the divalent peak is less intense. At this temperature the weak contribution from the intermediate state following 2p–4f quadrupolar excitation is observed (see Fig. 6[link] for more details).
