The dynamics of Lennard–Jones fluid is studied through extended mode coupling theory (MCT) with the inclusion of the slow mode of defect density. Inclusion of defect density facilitates the liquid like state for temperatures much lower than predicted from ideal MCT. In the present paper we consider the secondary relaxation over time scales long compared to microscopic time scales but shorter than the final relaxation. Particularly we study the temperature dependence and wave number dependence of the relaxation process.
