Abstract:

Simple but very precise acoustical probes such as RUS can be combined with very sophisticated but less accurate probes such as inelastic neutron scattering and diffuse neutron scattering to provide a powerful picture of the vibrational spectrum of a solid. Such a picture can be used to extract information about fine-scale microstructure, phase transformations and more. We describe here recent work applicable to martensites and Pu.
