These observations, together with previous results on ion implanted samples, point towards interactions of the conduction electrons with a layer of localized moments on the surface.doi:10.1016/0038-1098(77)91132-2A. StesmansJ. van MeijelJ. Witters...

The interaction Hamiltonian for the Coulomb exchange effect between conduction electrons and magnetic-shell electrons in rare-earth metals was derived from first principles. The approximations under which the interaction can be represented by the product of electron and ion spin vectors are exhibited. (...

The electrons produced in the thermal energy associative ionization reaction U + O 2 → UO + 2 + e were energy analyzed. Most of the exoergicity (≈4 cV) of the reaction appears to be retained by the ion in the form of internal energy while the electron emerges with only a small kin...
