Abstract
Structural relaxation in viscous glycerol has been followed from 5.9 p s 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 sh ows no significant temperature dependence; the mean relaxation time sc ales accurately with viscosity. Interparticle correlations decay slowe r and with less stretching than self correlations at similar wave numb ers. (C) 1996 American Institute of Physics.
