Abstract
Low-temperature expansions for the second moment of the spin density correlation function have been developed for a generalized ising model which includes three- and four-body interactions. The evidence for a downward shift in the value of gamma minutes +2nu minutes for a three-dimensional pure triplet ising model, which was previously predicted by the thermodynamic functions and scaling theory is well confirmed.Keywords
