‘‘γ-α’’ Phase Transition of Monolayer Ce on W(110)Physical Review Letters
AbstractAs Ce is adsorbed on a W(110) substrate at 300 K an epitaxial layer develops at a coverage of 0.5 monolayer. LEED patterns indicate a hexagonal pattern consistent with Ce(111). As Ce is added, the lattice parameter shrinks continuously from 9% larger than that for γ-Ce to 3% smaller than that for α-Ce. 4f photoelectron spectra reveal two peaks similar to those of γ-Ce, changing relative intensity with increasing coverage to resemble those of α-Ce.
