Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Vibrational fine structure has been observed in the Cls and O1s photoelectron lines of CO adsorbed on Ni(100). This allows a detailed separation of vibrational and electronic contributions to the line profile. The main line is found to represent the fully

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- System dependent effects in resolving vibrational fine structure in the corn-level lines of adsorbates are discussed. The example is carbon monoxide on transition metals. The importance of dynamic metallic screening is exemplified and the role of shake-up

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The origin of one- and two-step behavior of core-hole decay processes is identified in connection with high resolution autoionization spectra for Ar/Pt(111). The spectra simultaneously show features of the two types (resonant Raman vs Auger-like behavior)

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- The basis for resonant photoemission is discussed in connection with data for a physisorption system, Ar/Pt(111) and a 3d transition metal, Ni(100). For Ar/Pt(111) the quasi-localized character of the intermediate state leads to two types of features in t
