Quasielastic Neutron Scattering: An Advanced Technique for Studying the Relaxation Processes in Condensed Matter

Abstract

Quasi-elastic neutron scattering (QENS) is a part of more general inelastic neutron scattering and is a very powerful technique to explore the motions in biomolecules, polymers, simple liquids, alloy melts, and soft matter in general. In this chapter, we will discuss basic theoretical aspects of QENS, instrumentation, types of motion in liquids and solids, understanding these motions from the QENS data, and recent studies using QENS.
