摘要

Maximum Entropy is applied to the crystallographic imaging of x-ray diffraction data in order to reveal reliable model-free weak electron density features (if any ) in newly discovered high-T_c superconductors. The use of suitably computed non-uniform priors turns out to be essential. The suggested maxentropic procedure shows that about .2 oxygen atoms [ 1.6 electrons ] can unambiguously be evidenced near the much heavier mercury atoms [ harboring 80 electrons each], and this from standard laboratory [ non-synchrotron ] x-ray data.
