Abstract
In this review, we discuss the angular anisotropies in the scattering facto rs of electrons and positrons for scattering by atoms in solids. We show th at, as a function of the angle, the maximum number of dips in the scatterin g factor's magnitude and jumps of near pi in its phase are related to the a ngular momenta of the bound and resonance states of the potential. The effe ct of the scattering factor's anisotropies on low-energy electron and posit ron holographic wave-front reconstruction is discussed.
