* ABSTRACT
X-ray absorption near edge spectroscopy (XANES) were used to investigate the hole states in the La0.7Ce0.3MnO (LCeMO). A substantial decrease in the spectral weight of the eg orbital was observed in LCeMO compared to that in the hole-doped La0.7Ca0.3MnO. This directly proves that electron doping occurs in LCeMO. Furthermore, the possible scenarios of the electronic structure of LCeMO are discussed.
