Abstract [en]

It is well known that the structure information through the use of Spin Polarised LowEnergy Electron Diffraction (SPLEED) is highly sensitive to the interaction potentialbetween the primary electrons and the electrons of the target, especially to the exchangeinteraction. Since the electrons in SPLEED penetrate the surface only a few latticespacing, it is extremely sensitive to the spin structure of a magnetic surface. The earlystudy of Feder [1] on Fe(110) provides a strong indication in this direction. The mainobjective of this work is to use the insights of our recent work [2,3] to study the spinpolarisation of the exchange-correlation potential. The differential cross sections for electronscattering from atoms with net spin, namely nickel and iron, have been calculated togetherwith studying the energy/wave vector dependence of the exchange scattering from surfacesof nickel and iron in glasses by calculating differential cross sections and the spin asymmetryusing Dirac equation. Comparison of predictions with observed spin dependent scattering intensities in amorphous magnetic alloys will give insight into surface magnetisation in these systems[4].

Abstract [en]

Quantum mechanical calculations of a modification of the X-ray scattering form factor of an atom/ion in an electric field using a three parameter wave function have been performed. These calculations are compared with the previous two parameter wave function calculations.
