| Popis: | Synchrotron radiation photoemission has been used to examine interface reaction of overlayers of V and Ca deposited onto clean surfaces of the bulk hydride YH2 and the deuteride NbD0.75. Changes in the hydrogen‐induced bonding bands and the d bands near EF and variations in the intensities of the substrate core level emission as a function of metal coverage indicate that hydrogen diffuses from the substrate into the overlayer. The results are discussed in terms of the mechanism for hydride formation. |
