We study the change in the electronic structure of (Formula presented) across the δ-controlled metal-insulator (M-I) transition. X-ray-absorption spectroscopy shows the formation of hole states with substantial (Formula presented) character as a function of δ. Ultraviolet photoemission spectroscopy confirms the gap (Formula presented) closure across the M-I transition due to the doped hole states. The results show that a Mott-Hubbard system can have a charge-transfer character due to the strong hybridization, indicating a very mixed character ground state.
