Abstract

The dynamics of supercooled toluene, studied in a GHz-THz range by incoherent neutron and depolarized light scattering, is found to be in full accord with mode coupling predictions. Around the susceptibility minimum, neutron spectra are wavenumber independent and proportional tolight scattering data; the fast beta-relaxation scaling law applies; amplitude and frequency diverge with power laws that extrapolate towards a crossover temperature T-C = 143 K.
