We present an X-ray photoemlsslon spectroscopy study of some rareearth ion(IU)excha Y-type z+oIites (Ln-u). The 4f levels of Eu-Y mere drastxally changed by degassmg at low temperature; the relatwe intensity of the 4f levels for Eu3 + decreased and the 4f lme of Eu'+ increased as the sample was dega
The dehydration of RENaY, where RE --La 3รท and Ce 3+, has been studied by the 129Xe n.m.r, technique. The [RE (OH)=] {3-')+ cations migrate from the supercages toward the prisms and sodalite cages when x = 0 for La 3+ and x = 0 or 1 for Ce 3+. The chemical shift bs.RE of the xenon adsorbed by the to
