The diffuse neutron scattering intensities for CuI and AgBr were analyzed by the theory including the thermal correction effects up to 3rd nearest neighboring atoms. When we include the temperature dependence of the values of correlation effects, the obtained results by the refinement were improved than the former. The values of correlation effects decrease rapidly with the increase of inter-atomic distance. The values also decrease with the decrease of temperature.
