We present a new neutron-scattering approach to access the van Hove distribution function directly in the time domain, I(t), which reflects the system dynamics. Currently, I(t) is essentially determined from neutron energy-exchange. Our method consists of the straightforward measurement of the running time-integral of I(t), by computing the portion of scattered neutrons corresponding to species at rest within a time t, (conceptually elastic scattering). Previous attempts failed to recognise…

Experimental demonstration of the novel “van-Hove integral method (vHI)” for measuring diffusive dynamics by elastic neutron scattering

It is shown that vHI works in practice, which is achieved by using a simple modification to the standard QENS backscattering spectrometer methodology via a step-wise variation of the frequency of the monochromator Doppler-drive, providing a measurement of the vHI profile at the detectors.

Determining the relaxation time from a temperature-dependent scan of the neutron spin-echo signal amplitude

Temperature-dependent scans of the neutron scattering intensity are commonly employed in high energy-resolution quasielastic measurements. Besides serving as a useful diagnostic tool for identifying

A Quantitative Comparison of the Counting Significance of van Hove Integral Spectroscopy and Quasielastic Neutron Scattering

This work focuses on the efficiency of the vHI method compared with the standard quasi-elastic neutron scattering (QENS) method, using a numerical Monte-Carlo simulation of an instrument that is equally capable of measuring QENS and vHI under identical conditions.

By fitting to experimental data obtained on a protein solution the present methodology is used to show how the existence of a temperature-dependent relaxation frequency can lead to a transition in the measured mean-square displacement in the absence of an EISF change.
