Abstract
The dimensions of single polyelectrolyte chains of increasing length a re investigated with off lattice Monte Carlo simulations. It is found that the expansion factor of the mean square end to end distance alpha (R)2 scales with uN3/2 for chain lengths N between 10 and 100 in the w hole range of the adimensional electrostatic coupling constant u. The agreement with the predictions of the mean field theory of dilute poly electrolyte solutions in a theta solvent without added salt is discuss ed. The scaling laws are verified by our experiments, which suggest al so the scaling behavior of the ''shape'' of the chains.
