Dynamic structure factors definition

The self-dynamic structure factor of the solute at all time is calculated from the mean square displacement (MSD) using the following definition ... [Pg.198]

By definition, the dynamic structure factor accounts for the correlations between the positions of the particles at different moments of time ... [Pg.318]

Obviously, if found experimentally, the exponent -2 is only a sign of reptation motion but not a sufficient condition for it. Thus, in order to prove that reptation is a really dominant mode of chain motion in polymer concentrates, we have to test it not only with self-diffusion but also with other physical properties which reflect the local motion of polymer chains. One such property is the (coherent) dynamic structure factor 5(fc, r) (see Section 3.2 of Chapter 4 for its definition). In fact, it was predicted theoretically [45-47] that the k dependence of its decay with r in the range of k defined by... [Pg.261]
