Abstract

Quasi-elastic neutron scattering(QENS) at small momentum transfer(Q) is related to the self-diffusion and that at higher momentum transfer related local jump motion. Motions of hydrogen in inorganic oxides, porous materials and organic polymer gels were constituted through the moving with water molecules, local jump between trapped sites and other moving modes. The QENS experiments provided the Q and energy(ω) transfer region, which correspond with each moving modes. As the obtained broad QENS spectra contain many moving modes, careful analyses should be necessary by reliable experimental data using a facility with high-resolution, wide momentum-transfer spectrometer and high neutron flux.
