Soft X-ray photoemission spectroscopies have been performed on YbCuGe, which is thought to be a Yb divalent system, to investigate its bulk electronic structure including Yb 4
electrons. Small but finite Yb
multiplet peaks were found at 6
12 eV in the angle-integrated spectrum, suggesting that it is a valence fluctuation compound. An "anti-crossing" Yb 4 bands with conduction bands were observed in the angle-resolved spectrum. This is the evidence that the Yb 4 electrons form a band state through the hybridization with Ge 4
and Cu 3
electrons.
