Theory of spin-polarized optical potential

Hatakada, K. ; Fujikawa, T. and Hedin, Lars LU (2001) In Journal of Synchrotron Radiation p.210-212
Abstract
We develop an approximation for the non-local spin-polarized optical potential theory for atoms in solids at intermediate and high energy. The present approximation for the optical potential builds on the GW-expression. We separate the RPA polarization propagator into a core electron and a valence electron part, and can then achieve a corresponding separation of the optical potential. For the valence electron optical potential we use a local density approximation because the charge density changes fairly slowly, whereas we use a non-local optical potential for the core electron part. Both of them depend on the spin-polarization. We apply this method to electron-Fe elastic scattering in solids, and discuss the results.(16 refs)
