Results of inelastic neutron scattering experiments between 300 K and 900 K on the relaxor ferroelectric PbMg<Subscript>1/3</Subscript>Nb<Subscript>2/3</Subscript>O<Subscript>3</S ubscript> are presented. Within a mode-coupling analysis the data are consistent with the observation of a strongly damped quasi-optic excitation.
