Standing waves and reflectivity from an ultrathin layer

Abstract

We have analytically found that the reflectivity amplitude from one thin layer in the presence of the other reflecting layers is modulated by the squared amplitude of the radiation field but not by the first-order amplitude, as was supposed in the paper of R. Röhlsberger (Hyperfine Interactions 123/124, 455 (1999)), for delayed nuclear resonance reflectivity. Hence, a larger sensitivity to standing waves is expected for the reflectivity signal from selected groups of atoms or nuclei compared with the secondary radiation emission.
