Abstract
We have constructed high-order T = 0 expansions for the elementary exc itation spectra, and high temperature expansions for the susceptibilit y, for the S = 1/2 Heisenberg antiferromagnet believed to describe the spin-gap system CaV4O9. Existing susceptibility data are analyzed usi ng these theoretical results. If nearest- and second-neighbor interact ions are in the ratio 2:1, there should be clear indications in both n eutron and Raman Scattering.
