Diffuse neutron scattering profile of KBr at room temperature was explained by including the correlation among thermal displacement of atoms up to third neighbor atom in the crystal KBr. The values of correlation effects decrease with inter-atomic distance. The diffuse scattering theory including correlation effects is applied as background function in Rietveld analysis.
