摘要：

Application of mica in the crystal analyzer of time-of-flight spectrometer installed in a pulsed cold-neutron source is a new approach in high-resolution neutron spectroscopy. We constructed a new set of mica-crystal analyzers for the neutron spectrometer at KENS (KEK), that gave a desirable performance of energy resolution accompanying by a surprisingly sharp rise shape of the resolution function. The latter characteristic was especially indicative of the usefulness of a mica-crystal analyzer in the quasi-elastic neutron-scattering studies of localized random motions in condensed matters.
