Abstract

Different methods and approximations for calculating reflectivity curves from scattering-length density profiles are carefully discussed and compared. Dynamical theory and the approximations leading to single-scattering dynamical theory, kinematical theory with an optical path-length correction and kinematical theory with refraction corrections are described. The differences are illustrated by calculations for model profiles for which dynamical effects are important.
