摘要：

Structural relaxation in viscous glycerol has been followed from 5.9 ps to 3.7 ns by coherent neutron scattering around the structure factor maximum. In a 100 K interval, the line shape of the decay function shows no significant temperature dependence; the mean relaxation time scales accurately with viscosity. Interparticle correlations decay slower and with less stretching than self correlations at similar wave numbers. (C) 1996 American Institute of Physics.
