The Resonance Scattering Phenomenon of Fast Negatively Charged Particles in a Single Crystal: http://arxiv.org/abs/1501.02244

The energy spectrum of the extended attractive potential of a crystallographic row for negatively charged particles has quasi-bound states. It follows that a negatively charged particle with small transversal momentum component (p ⊥R<<1) may undergo resonance scattering. Thus the resonance scattering phenomenon can be observed in a single crystal, when fast electrons move with a small glancing angle (θ0<<1/pR) to a crystallographic axis. The calculated results for the electrons and angular widths of resonance peaks are consistent with experimental data.
