Analysis of multiple scattering and multiphonon contributions in inelastic neutron scattering experiments

Abstract

We present a method of analysis of inelastic neutron scattering (INS) experiments aiming at obtaining the density of phonon states in an absolute scale, as well as a reliable value of the mean-square displacement of the atoms. This method requires the measurement of the neutron total cross section of the sample as a function of energy, which provides a normalization condition for the INS experiment, as well as a value of the mean-square displacement. The method is applied in the case of an incoherent neutron scattering system, viz. the Ti–52wt.% Zr alloy. The applicability of this method to the study of metal alloys and other systems is discussed. 2002 Elsevier Science B.V. All rights reserved.
