Query: Analysis of occupational and displacive disorder using the atomic pair
  distribution function: a systematic investigation   Many disordered crystalline materials show chemical short range order and
relaxation of neighboring atoms. Local structural information can be obtained
by analyzing the atomic pair distribution function (PDF). The viability of
reverse Monte Carlo (RMC) simulations to extract quantitative information about
chemical ordering as well as displacements is investigated. The method has been
applied to simulated PDFs of disordered structures showing chemical disorder
alone as well as in combination with displacements.
