Résumé
Eur. Phys. J. B, 13, 83 (2000) We present a detailed analysis of the beta-relaxation dynamics of a simple
glass former, a Lennard-Jones system with a stochastic dynamics. By testing the
various predictions of mode-coupling theory, including the recently proposed
corrections to the asymptotic scaling laws, we come to the conclusion that in
this time regime the dynamics is described very well by this theory.
