Abstract

The Debye-Waller factor of the van der Waals glass tri-α-naphthylbenzene, measured by high resolution incoherent quasielastic neutron scattering, shows a cusp at T_c=407±5 K signaling the existence of a critical instability as has been predicted by mode coupling theory to occur in supercooled glass forming liquids. At temperatures above T_c structural relaxation is observed to obey the time-temperature superposition principle.
