Insights into Inelastic Neutron Scattering and Crystal Dynamics: Phonon Dispersion Relations

This document provides a comprehensive exploration of inelastic neutron scattering and its implications for the dynamics of crystals, particularly focusing on phonon dispersion relations. The study covers essential aspects such as the transverse optical and acoustic modes in diatomic chains, along with dispersion relations in various materials including α-SiO2 and Germanium. The use of three-axis spectrometers, specifically the IN14 setup, is detailed, showcasing selected results that aid in the understanding of phonon behavior in crystalline structures like CaF2, urea, and carbon nanotubes.
