Abstract

The effects of chemical binding energy on neutron total cross section were investigated by means of elastic and inelastic neutron scattering techniques. The metal hydrides Ti0.45Cr0.45Mo0.1D1.8 and Ti0.48Cr0.32V0.2D1.8 were used for the experiment, for which the expected effects can be detected via the observed dynamics of deuterium (D). The D local mode was observed by inelastic measurement at ∼100 meV for the first-order excitation, and higher order vibrational modes up to n = 4 were observed. Apart from these ordinary local vibrations, a specific energy potential â., ω 0 in the system was observed by elastic measurements as a recoil effect. It is found that the wave length dependence of the incoming neutron largely affects its intensity even for a coherent cross section. The effect should be taken into account particularly for the analysis with time-of-flight technique of pulse neutron diffraction.
