- W145331325 abstract "Bederson first summarized the requirements of the {open_quotes}complete{close_quotes} scattering experiment, in which the magnitudes and phases of all scattering amplitudes would be determined as functions of both scattering angle and energy of the collision partners. Ever since, both theorists and experimentalists have been devising more intricate and illuminating combinations of polarized projectiles and spin- and angular momentum-oriented targets, and ever more novel techniques for increasing the resolution, if you will, of spin and angular momentum transferred during the collision. The {open_quotes}complete{close_quotes} experiment has yet to be performed, but great progress has been made, particularly for relatively simple targets such as sodium and cesium. For these hydrogen-like systems, the number of parameters needed to define the {open_quotes}complete{close_quotes} experiment is at a manageable minimum, but the alkalis` greater nuclear charge increases the impact of spin-dependent forces, such as the spin-orbit interaction. Thus the possibility of obtaining useful insight from calculations or measurements is maximized. This talk will focus, for these two atoms, on selected theoretical and experimental results for spin-dependent effects, such as the {open_quotes}fine-structure{close_quotes} effect, that do not require the use of polarized electrons; for spin-dependent effects such as the pure exchange interaction, that do require the use of polarized electrons;more » and, for cesium, results that begin to elucidate effects in the scattering process that do not emerge until one steps beyond the constraints of the non-relativistic Schrodinger equation.« less" @default.
