Spin Polarization in Proton-Xenon Charge Exchange Collisions
The production of spin polarized particles by collisions between initially unpolarized particles has been of continuing interest since the early theoretical work of Mott1 on elastic electron scattering. In the subsequent forty years various experiments have been devised to polarize elementary particles, particularly electrons and nucleons, by this method. Compound systems including light nuclei can also be produced by scattering from unpolarized targets. Conspicuously absent from the list of particles which have been spin polarized by scattering are atomic atoms and ions, particularly the hydrogen atom. Their absence is due to the availability of other techniques for polarizing atoms, such as atomic beam and optical pumping techniques, and to the lack of a suitable reaction. In this paper we propose a suitable reaction,2 and report detailed calculations of the spin polarization.
