N2 - 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 Tc=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 Tc structural relaxation is observed to obey the time-temperature superposition principle.
