Times Cited Count:5 Percentile:79.39We have investigated the effect of hydrogenation on La and electronic states in metallic LaH by X-ray absorption near edge structure at the La -edges. As the hydrogen content increases from 0 to 2.6, white-line intensity at the La -edges shows a remarkable increase in the range of 2.0. This is interpreted as the increase in La hole induced by interstitial H atoms on the octahedral sites. On the other hand, the shoulder structure at the La -edge disappears in the process of = 0.0 2.0, indicating that the - hybridization is weakened by H atoms on the tetrahedral sites. This study demonstrates that H atoms on the two interstitial H sites provide different contribution to the modification of the electronic states.
