摘要：

A method is proposed for the determination of the phase of the reflection coefficient, which can be applied even in the regime of total reflection. It exploits the interference of the spin components of a polarized neutron beam in the presence of a magnetic field and requires the measurement of polarizations. The results of a simulated determination of the complex reflection coefficient are used as input for the calculation of the surface profile by inversion. (C) 1998 Elsevier Science B.V.
