摘要：

We present an extension of the invariant-embedding R-matrix method for calculating wave functions in reflection high-energy electron diffraction (RHEED). Using this method, we study the strong resonances commonly observed in RHEED rocking curves. Results for an Ag(001) slab show that the resonances are associated with the trapping of diffraction beams inside planar layers and the angles at which these resonances occur can be identified by the minima in the total elastic flux. The penetration of the electron wave field inside a slab is shown to be a few monolayers deep.
