Spin-Spin Correlation Function of the Three-Dimensional Ising Ferromagnet Above the Curie Temperature

High-temperature series expansions for the Ising model's spin-spin correlation function are found to order (J{kT) }^12 on the simple cubic, bcc, and fcc latices. Analysis of moment series indicates that the scaling form of the correlation function is correct, at least in the limit fixed, 0. Values are obtained for the correlation indices and -the latter by two methods, thereby providing a direct check on the scaling law.
