The Fe62Ni20Cr18 valence band was studied by scanning the photon energy across the 2p(3/2) core-level threshold of each element of the alloy. A resonant enhancement of the weak 3d-like features was observed. In pure transition metals, similar valence

The C 60 molecules are known to bind covalently to the Pt(1 1 1) surface. We performed a structural study of one C 60 layer on Pt(1 1 1) by using X-ray photoelectron diffraction (XPD). Our results show that the molecules are bonded to the metal surfa

The atomic-like behavior of the photoionization cross-section of core levels in solids is remarkably displayed in the observation of linear magnetic dichroism in the angular distribution of photoelectrons. Structure-related effects are clearly visibl
