Abstract
The dynamic correlation function for an isotropic ferromagnet forT≧T c is calculated in first order in ε=6−d. Applying an exponentiation procedure then leads to results which are relevant for the analysis of neutron scattering experiments in the vicinity of the critical point.

In Eq. (24) of Ref. 12 the correct value ofb 0 should be zero. (Eq. (23) certainly should readF(x)=−1/8ln ix+...)
