Abstract
We perform a finite size analysis of the longitudinal and transverse structure factors in the groundstate of the spin- XXZ model. Comparison with the exact results of Tonegawa for the XX model yields excellent agreement. Comparison with the conjecture of M\"uller, Thomas, Puga and Beck reveals discrepancies in the momentum dependence of the longitudinal structure factors.
