Phys. Rev. B 62, 10377–10382 (2000)Phase determination of x-ray reflection coefficientsReceived 4 May 2000; revised 29 June 2000; published in the issue dated 15 October 2000 It is shown to what extent the phase of a reflection coefficient may be determined from a single x-ray reflectivity experiment. Complex calculus guarantees that the so-called “phase problem” is relaxed for certain situations and the reflection coefficient is only determined by its moduls. A procedure to reconstruct the phase from a single measurement under incorporation of preknowledge of the system is derived and tested by numerical examples. © 2000 The American Physical Society URL:
