Standard screening potentials can cause volume refraction for negative particles.

Positive particles typically undergo volume reflection, contrasting with negative particles.

Abstract

The volume coherent deflection of high-energy positive and negative particles in uniformly bent crystals is studied. The general analysis of potential scattering shows that the standard screening potential for a large class of collisions can cause the volume refraction for negative particles (antiprotons, electrons) instead of the volume reflection for positive particles (proton, positrons).
