Data processing method for neutron diffraction experiments

We present a procedure to perform multiple scattering, attenuation and efficiency corrections in reactor neutron diffraction experiments, based on a Monte Carlo code applied iteratively. We discuss the application of two procedures, the first based on Granada’s synthetic model, useful for incoherent scatterers, and the second, based on the measured experimental distributions for coherent scatterers. Experiments on samples of polyethylene, light water, heavy water and Teflon of different sizes were performed and the correction procedures are tested. The problem of normalization in an absolute scale in diffraction experiments is addressed and results obtained from the present procedure are shown.
