Abstract
The zero-field, two-point correlation function of an -vector system in dimensions is calculated to order for . The scaling function is obtained as a closed, cutoff-independent integral. As at fixed wave vector , the leading variation is , where is the specific-heat exponent; thence the maximum in the scattering above is located, in good agreement with high- series-expansion estimates.
