Resonance Scattering of Fast Electrons in a Single Crystal

TL;DR

This paper demonstrates that resonance scattering occurs for fast charged particles in extended crystal potentials, providing a new interpretation of small-angle electron scattering data in crystals.

Contribution

It introduces the concept of resonance scattering in extended potentials and applies it to interpret experimental data on electron scattering in crystals.

Findings

Resonance scattering occurs in extended crystal potentials.

Small-angle scattering data can be explained by resonance effects.

Theoretical interpretation aligns with experimental observations.

Abstract

It is shown that resonance scattering of fast ($pL > >pR > > 1$, $p$ is the particle momentum, $L$ is the longitudinal dimension of the potential, and $R$ is its transverse dimension) charged particles occurs in the extended potential. The data on small-angle scattering of fast electrons in the crystal are interpreted on the basis of the examined effect.
