New Experiments with Electron Capture Spectroscopy at Ni, Gd and Cr Surfacesperformed with electron capture spectroscopy ECS at surfaces of oligatomic epitaxial Ni(100)-films, of polycrystalline thin films of Gd, of bulk Gd and of bulk Cr(100)crystals. The results are that the ESP at surfaces of oligatomic (2–64 layers) epitaxial Ni(100)-layers depends on the Ni-layer thick

Electronic Excitation in Ion-Molecule Collisions to many fruitful insights. Almost all of the connections made have been with information obtained from two body ion-atom collisions via an intuitive leap to a solid which in some cases may be treated as a molecule with an almost infinite number of atoms. Here we will attempt to introduce some infor

Plasma Effects in the Theory of Charge Fractionse charge fraction of protons . is defined in terms of the number of backscattered protons, n. of hydrogen atoms, n., and of negative hydrogen atoms, n.. It was found that for low velocities n. is proportional to the kinetic energy of the backscattered particles. This important result holds true for

Polarization of Balmer Radiation from Grazing Incidence Collisions of Protons on Surfaceseffort is directed at elucidating the mechanisms of formation and destruction of anisotropically populated excited states at surfaces. This has relevance not only to grazing incidence experiments, but also to ion backscattering, sputtering, transmission through foils, and in general the interactions

,α Polarization After Electron Capture in Ion-Surface Interactionolarization of the subsequently emitted light is determined by evaluating the Stokes’s parameters. The contribution of electron capture from localized target-electron states is compared with capture from conduction electrons. The role of electron-loss processes is discussed and the influence of the

Electron Emission from Solids During Ion Bombardment. Theoretical Aspectsestimated on the basis of the free-electron-gas model of a solid. We find that the neglect of elastic scattering of electrons in most existing treatments of electron emission has severe consequences on the interpretation of structure in measured electron spectra. Comments are made on the escape dept

New Experiments with Electron Capture Spectroscopy at Ni, Gd and Cr Surfacesues above the bulk Curie temperature TCb = 292 ? demonstrate that ferromagnetic order at the surface exists beyond T.,. ECS measurements at surfaces of anti-ferromagnetic bulk Cr(100) crystals clearly show that the topmost atomic layer is ferromagnetic.
