Abstract
A peak in the static structure factor of a Bose-Einstein condensate is computed, both near and far from a Feshbach resonance. A low-density approximation is made, allowing for an analytic result. A Monte Carlo calculation shows that the peak is larger than predicted by the low-density approximation, for the upper range of densities considered here. The peak could be measured by a probe beam of cold atoms.
