Computer simulation studies of static and dynamical scaling in dilute solutions of excluded-volume polymers

We have used a novel Monte Carlo method to compute the gyration radius Rc and the hydrodynamic radius RH of excluded-volume polymer chains. The hydrodynamic radius scales as Ng05s (N is the number of bonds) over at least a decade of chain lengths, whereas the gyration radius exponent is close to the theoretical value of 0.59. The anomalous behavior Of RH is well-known experimentally; it is commonly
