Extracts (1.2 < d < 2.4 Å) from the diffraction patterns recorded in the back-scattering detectors from BaBiO3 in each of its four phases. Crosses represent the observed data. The peaks are indexed on the parent perovskite (ca 4 Å) cell. The peaks with fractional indexing are superlattice peaks arising from cation ordering (or rather the associated oxygen displacements) and/or BiO6 octahedral tilting. The low-temperature patterns show a weak contaminant peak from stainless steel (ss). The structures were identified from the main-peak splittings and the presence or absence of superlattice peaks. The continuous lines are fits obtained by the Rietveld method assuming the indicated structures.
