Reexamination of super-lattice reflections corresponding to 2b, 2c by X-rayreveals no exsistence of such a superlattice structure in the paraelectric andferroelectric phases. In the paraelectric phase, however, interesting diffuse scat-terings are observed around reciprocal points wltere the super-lattice reflectionswere expected. In the ferroelectric phase, only the super-lattice reflections cor-responding to 2a are observed, and no diffuse scatterings are observed as in theparaelectric phase. It is confirmed that the true space group is Pnam in the para-electric phase, and Pn2.a in the ferroelectric phase.
