Powder neutron diffraction measurements were performed on the compounds Pb^Sr~Y. Ca Cu.0A+ ~ ~ A-X X (x O, 0.5) to determine the structural parameters, especially the coordi~ates and occupation of the oxygen sites. A comparison is made between the structures of the superconducting (x = 0.5) and non-
Neutron and X-ray powder diffractograms of the title compound were refined by the Rietveld method. Within the bismuth layer an additional oxygen site with population parameter 0.12 was found which is interpreted as the excess oxygen. From the comparison of population parameters from neutron and X-ra
