ABSTRACT: From current research activity we have begun to observe and control the interplay between electron correlations, electron exchange, spin-orbit coupling, and field distortions within compound atomic structures. The studies of these physical interactions have accumulated from spin-polarized electron momentum probing exchange and spin-orbit coupling in free single atoms as well as spin polarized momentum dispersion in multilayered thin films and surfaces, elemental momentum density dispersion in doped perovskite oxides and in polymer blends such as polyvinyl and polyacetates using positronium coincidence doppler broadening for surface depth probing of elemental electron density dispersions. Our discussion will concern such concepts at an introductory level.
