Abstract
The magnetic susceptibility and the correlation length of the 0(N) non-linear two-dimensional σ-model are constructed from their high temperature expansions at 14th order and asymptotic scaling. For N = 3 and N = 4, this determination is compared with Monte-Carlo data and used to predict the onset of scaling at finite coupling.
