Complete determination of the reflection coefficient in neutron specular reflection by absorptive nonmagnetic media
An experimental method is proposed which allows a complete determination of the complex reflection coefficient for absorptive media for positive and negative values of the momenta. It makes use of magnetic reference layers, and is a modification of a recently proposed technique for phase determination based on polarization measurements. The complex reflection coefficient resulting from a simulated application of the method is used for a reconstruction of the scattering density profiles of absorptive nonmagnetic media by inversion.
