摘要：

From a comparison of the experimental yields with the calculated ones is found that the oxygen sublattice is partly disordered (about 15-20% of the oxygen atoms displaced from the crystal sites in the La-Cu-O rows). The thermal vibrational amplitude of the oxygen atoms in the plane perpendicular to the O-O rows is apparently less (0.07 angstrom) than derived from the Debye model (0.15 angstrom).
