    Abstract

    Critical neutron scattering around a superlattice reflection above Tc yields information on the pair correlation function for occupation of lattice sites. The Ornstein-Zernike correlation function e-k 1 r/r is proved to fit the data excellently, and at 8.9deg K above Tc the inverse correlation range k 1 is found to be 0.0615 Aring-1 with an estimated uncertainty of plusmn2%. Correction for instrumental resolution is an essential part of the interpretation of the data and is described in detail.
