摘要：

The Marchenko inversion method is employed to determine the scattering-length density profile from the reflectivity for a number of realistic cases. Phase information is obtained via a logarithmic dispersion relation connecting the reflection phase with the reflectivity. The remaining ambiguities to be resolved by phase measurements are analyzed. Their importance for a unique determination of the profile is illustrated.
