摘要：

The local environments around hydrogen atoms in a hydrogenated amorphous LaNi5.0 film have been investigated by neutron diffraction and were compared with those in a hydrogenated crystalline bulk. From the pair correlation functions for amorphous LaNi5.0Dx (x = 0, 2.5), the interatomic distances of D-Ni pairs were found to be longer for the amorphous LaNi5 than for the crystalline bulk, indicating that hydrogen atoms in the amorphous LaNi5 occupy the distorted hydrogen sites suggested from an extended X-ray absorption fine structure analysis. Furthermore, the hydrogen atoms absorbed in the amorphous LaNi5 prefer to occupy the La2Ni2 tetrahedral site rather than the La2Ni4 octahedral site in comparison with the case of the crystalline LaNi5.
