Abstract : The exponent ν describing the configurational properties of an isolated polyelectrolyte chain in dimensions 3 < d ≤ 7 is determined using Monte Carlo methods. Freely jointed chains consisting of up to N = 320 rigid links are considered. We find an end-to-end distance R ∼ Nν with ν = 3-d which is in agreement with self-consistent calculations and Flory type theories. It differs from zero component Lagrangian theory and real space renormalization group calculations which give ν = 2-d - 2 for 4 < d ≤ 6.
