At present, the contrast that can be detected by scattering experiments is of order several percent (ef. e.g. the neutron diffraction study in propylene glycol by Leheny R.L., Menon N., Nagel S.R. et al, J. Chem. Phys. 105 (1996) 7783-7794). Typical values of ζα (a few nanometers [10]) would correspond to a slight variation of the scattering factor S(q) in the crossover from the fluctuation plateau to the first peak in S(q). At present negative evidence does not allow to conclude that there is no characteristic length for glass transition, for the following reasons. The characteristic length is a dynamic or kinetic property of glass transition cooperativity which, in principle, needs not to be connected with a density correlation at all

(cf. e.g. Sappelt D. and Jäckle J., J. Phys. A: Math. Gen. 26 (1993) 7325). If the mobility variation is, however, coupled to local densities, the density effects are expected to be very small, since, as well known, very small changes of free volume have large effects on mobility. Moreover, the theoretical approach used here can also be based on a "free entropy" [21]. This would give an entropy (or structure) pattern that does not inevitably imply a density pattern. Moreover, a part of local structure or configuration fluctuations can be lost by the natural averaging included in scattering experiments.

α time scale (Fig. 3) we have many space points for a quasi-continuous description of the cooperative rearrangements in a CRR. This allows the extension of the description to very small parts of a CRR and to very small CRR's itself, e.g. in the onset region.
