  The scattering from crystals can be divided into two parts: Bragg scattering
and diffuse scattering. The analysis of Bragg diffraction data gives only
information about the average structure of the crystal. The interpretation of
diffuse scattering is in general a more difficult task. A recent approach of
analysing diffuse scattering is based on the Reverse Monte Carlo (RMC)
technique. This method minimises the difference between observed and calculated
diffuse scattering and leads to one real space structure consistent with the
observed diffuse scattering.
  The first example given in this paper demonstrates the viability of the RMC
methods by refining diffuse scattering data from simulated structures showing
known occupational and displacement disorder. As a second example, results of
RMC refinements of the diffuse neutron- and X-ray scattering of stabilised
zirconia (CSZ) are presented. Finally a discussion of the RMC method and an
outlook on further developments of this method is given.
