Description Neutron-inelastic and quasi-elastic scattering and diffraction techniques are used to study the vibrations, reorientations, and structure of molecular and complex ionic crystals, including

the structural changes of materials during indentation deformation. Recently, this methodology has been employed in in-situ studies on the phase transformation of crystalline and amorphous silicon thin films and
