INTERMULTIPLET TRANSITIONS IN RARE-EARTH-METALS

摘要: We report here on direct observations of intermultiplet (IM) transitions in the rare-earth metals, Pr, Nd and Tb, made using chopper spectrometers at Intense Pulsed Neutron Source Argonne National Laboratory. Despite hydrogen contamination polycrystalline samples, we have observed inelastic peaks small Q arising from IM Pr (approx.260 MeV), (approx.242 MeV) Tb (approx.256 although latter has not yet been unambiguously. Future work will investigate energy level structure dynamical properties ions stoichiometric metallic systems. 5 refs., 3 figs.
