Abstract
A detailed analysis is given of high-temperature series expansions for the susceptibility of an O(2)-symmetric spin model with discretely valued spin-spin interaction on SC, BCC and FCC lattices. This analysis indicates that the model is in the same universality class as the regular 3D O(2) spin model. New results are given for the critical amplitudes. The authors also list and discuss series expansions for the free energy and specific heat.
