The of melts obtained on the neutron time-of-flight spectrometer, FOCUS. The solid lines are from fits using the MCT -scaling law [Eq. (1)] with . The dotted lines are fits with the KWW function with in the -relaxation regime.
(a) The depends on the mean relaxation time of the -process rescaled using Eq. (3). The dotted lines are the linear fit crossing at zero, . (b) The temperature dependence of the amplitude and time scale of the -relaxation process according to Eq. (2). Both lines are extrapolated consistently to obtain the MCT at . The corresponding is .
depends on the inverse of observed for five different temperatures. At values, , which shows a linear dependence. The straight line is the linear fit and the slope gives the .
The of Cu atoms in the liquid as observed by QENS. The dotted curve is the -scaling fit to with and . The corresponding is .
