Direct solution of the diffraction pattern of a crystal with planar faulting

A direct formalism for the solution of the diffraction pattern from the faulted layer crystal is derived. The proposed method is not specific for any crystal structure. The solution avoids the need for specific planar faulting models and has a direct physical meaning. The correlation distribution function between lateral displaced layers can be directly obtained from the diffracted intensities. The solution was compared successfully to a Monte Carlo trial and error method for the fee structure. The developed formalism was used to determine the layer-layer correlation distribution function of the Gd2Co17 faulted layer structure.
