Abstract
Quasielastic neutron scattering has been used to study atomic dynamics in liquid Cu. At small wave numbers q the intermediate scattering function is dominated by incoherent scattering contributions. From the decay of the quasielastic signal, self-diffusion coefficients D are obtained on an absolute scale. In a temperature range from 1370 to 1620 K, D values exhibit an Arrhenius-type temperature dependence and are significantly smaller than those from previous tracer experiments that are hampered by convective flow.
