High-resolution core-level photoemission data from the 1s level of Li(110) have been obtained between 77 and 280 K. Analysis of the data reveals a significant difference in the zero-temperature phonon broadening between the bulk and surface atoms but

High-resolution photoelectron spectroscopy using synchrotron radiation is used to measure the binding energy of the W 4f{sub 7/2} core level associated with bulk atoms of a W(111) crystal in the temperature range from 80 to 780 K. As temperature incr

Above the threshold for K 3p excitation, the conduction band photoemission spectrum of metallic potassium is dominated by core excitation coupled to autoionization. This accounts for the observation of a strong response in regions where k-conserving

The difference between threshold theory and X-ray absorption-edge data in the near-edge region of simple metals is indicative of a reduction in screening response beyond threshold. An empirical model in which the edge exponent decreases linearly abov

Photoemission from the CsCl structure, n-type semiconductor CsAu confirms the presence of an adsorbed Cs layer on films produced by vapor phase reaction between bulk Au and Cs vapor. Cs 4d and 5p spectra yield a well-defined Cs core-electron binding-

Photoemission spectra of CaxC60, SrxC60, and BaxC60 show successive filling of the tlu-derived LUMO and the tlg-derived LUMO + 1 bands, for 0 < x < 6. For x < 2 compounds of Ca and Ba exhibit a well defined Fermi cut-off; compounds of Sr do not. In t
