Resonance in Atom Diffraction by Crystal Surfaces. III. Analysis of Isolated Resonance

Abstract

Column matrix which describes the amplitudes of diffracted waves is expressed in the form of the resonane scattering plus the direct scattering. A new equation which determines the position of resonance is obtained from the resonance term. The present theory is applied to calculations of the intensity versus azimuthal angle spectrum for the system D/NaF(001). Intensity profiles of an isolated resonance is analyzed in detail.
