We find that the intensity of white-line features at the Ni L3~-edge in the Ni3Al (Ni3Ga) alloy decreased in comparison with that of pure Ni, which can be attributed to the enhancement of Ni 3d states filling and the depletion of the density of Ni 3d unoccupied states in the Ni3A1 (Ni3Ga) alloy. Two clear features are also observed in the Ni3Al (Ni3Ga) XANES spectrum at the Al (Ga) K-edge, which can be assigned to the Al (Ga) unoccupied 3p (
