Abstract
Recently reported light-scattering studies of CaKNO3 and Salol are rea nalyzed, using the extended version of the mode-coupling theory of the liquid-glass transition including activated transport or hopping effe cts. Problems found in the original fits due to the neglect of hopping terms are largely corrected, and quantitative predictions for the sus ceptibility minimum below the crossover temperature T(c) are found. Th e results are also shown to accurately explain the CaKNO3 neutron spin -echo data reported by Mezei [J. Non-Cryst. Solids 131-133, 317 (1991) ].
