AbstractAbstract
[en] As the first part of an effort to systematically study the inversion problem in X-ray and neutron reflectivity experiments, closed-form expressions are derived for the reflection and transmission coefficients as functionals of the sample profile. The assumption used is that the reflection is mainly due to the first and the second order derivatives of the profile and thus the third and higher order derivatives are negligible. One of the two major characteristics of the formulas is that the reflection and transmission coefficients are explicitly expressed in terms of the profile; the other is that the formulas are valid over the entire range of momentum transfer Q. This procedure allows the straightforward calculation of the real space profile using the reflectivity data as the computer input, with an accuracy that still remains to be evaluated through both analytical and numerical analyses with the aid of model profiles.
