The spin polarized slow positron beam and the reemitted polarized slow positron spectroscopy

We have begun to construct the spin polarized slow positron beam. Our system is composed of the electrostatic lens, the Wien filter and the detector. Reemitted spin-polarized slow-positron spectroscopy is proposed for studying magnetic materials. We have evaluated the depolarized positron fractions versus the incident energy in a thin Fe film and View the MathML source multilayers.
