摘要
Compton profiles for polycrystalline Lu and LuH2.05 have been determined by Compton scattering of 320-keV photons from a Cr51 source. The profiles for pure Lu have been corrected for multiple scattering and compared to a renormalized-free-atom model for the conduction electrons. The Compton profile for metallic Lu suggests an electronic configuration close to 5d16s2. A model for the dihydride based on a band-structure calculation by Switendick in which a new band of antibonding hydrogen wave functions accommodates the two extra electrons per LuH2 explains the experimental Compton profile in a satisfactory way. © 1979 The American Physical Society.
