# Dynamics from elastic neutron-scattering via direct measurement of the running time-integral of the van Hove distribution function

@article{Benedetto2019DynamicsFE, title={Dynamics from elastic neutron-scattering via direct measurement of the running time-integral of the van Hove distribution function}, author={Antonio Benedetto and Gordon J. Kearley}, journal={Scientific Reports}, year={2019}, volume={9} }

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…
