Abstract
Calculation of the reflection and transmission coefficients of average-energy electrons at their normal incidence on a single-crystal thin film is carried out. The energy intervals between the diffraction maxima on the electron-reflection curve are determined. It is shown that, at average particle energies, a noticeable quantum-size effect is manifested for Bloch waves formed in a single-crystal film. Its manifestations are sufficient for experimental observation both on the reflection and transmission curves. Various experimental schemes are proposed. Thus, the possibility of observing the effect is indicated not only in the case of low-energy electrons (5–20 eV), which was known earlier, but also in the case of particles of average energy (10–20 keV).
