Abstract
Estimates for the critical exponent gamma for the initial susceptibility of the three-dimensional spin-1/2 Ising model are summarised. There is a discrepancy between estimates based on high-temperature series expansions and those obtained using renormalisation group theory. High-temperature series estimates for gamma are reviewed and re-examined using some new data. It is tentatively concluded that a small discrepancy still appears to exist and that further work is needed to resolve it.Keywords
