The scheme enables the production of a tagged, highly polarized antineutron beam.

Potential for new experiments in fundamental physics.

Abstract

A scheme is proposed for the preparation of a tagged highly polarized antineutron beam, so far not available for experiments. Unpolarized antineutron fluxes are expected to exceed previous intensities by more than an order of magnitude. The method used is based on electropion production on a stored antiproton beam.
