The low lying spectrum of the O(n) effective field theory is calculated inthe delta-regime in 3 and 4 space-time dimensions using lattice regularizationto NNL order. It allows, in particular, to determine, using numericalsimulations in different spatial volumes, the pion decay constant F in QCD with2 flavours or the spin stiffness rho for an antiferromagnet in d=2+1dimensions.
