Octahedral Site Occupation in Lanthanum Dihydride

Part of the NATO Conference Series book series (NATOCS, volume 6)


The distribution of hydrogen ions among the octahedral and tetrahedral sites in lanthanum hydride has been determined at liquid helium temperatures for hydrogen/metal ratios from 1.90 to 2.04. Electron spin resonance spectra of dilute erbium ions substituted for host metal atoms establish the hydrogen site occupation adjacent to the erbium versus hydrogen loading. These data together with a lattice-gas calculation yield the site occupation versus hydrogen concentration in bulk lanthanum hydride, which is such that 2% of the octahedral sites are filled in LaH2.00.
