Zusammenfassung:We present a new approach to multiple scattering correction, based on a combination of taking experimental data at several incident neutron wavelengths and an iterative numerical evaluation of multiple scattering contributions. It allowed us to model independently determine the low intensity part of dynamic structure factor in a typical glass Ca{sub 0.4}K{sub 0.6}(NO{sub 3}){sub 1.4}. The new method makes the range of small momentum transfer in liquid and amorphous systems accessible for neutron inelastic scattering investigation and opens up new opportunities for the study of dynamic processes in these systems.
