摘要: Abstract The structure of the H and X high temperature forms La 2 O 3 Nd have been solved by neutron diffraction experiments performed on D1B multidetector powder goniometer I.L.L.: hexagonal form belongs to P6 /mmc space group cubic Im3m group. We propose a new crystallochemical principle which allows coherent description A-low form, forms. statistical resulting from partial oxygen disorder can be assumed either static or dynamic model.
