Abstract
The lattice constants and space group of undoped and lightly rare-earth doped BaCeO3 have been investigated using high-resolution neutron powder diffraction. The space group determined as Pmcn is unchanged from our earlier investigations; however, the lattice constants b and c have had to be reversed to account for additional reflections observed in the high-resolution diffraction pattern. The crystal structures of BaCe0.9Y0.1O2.95 and BaCe0.9Gd0.1O2.95 have been re-refined in the light of this observation.
