• The anisotropic temperature parameters of tetragonal BaTiO_3 are studied theoretically on the basis of thermal diffuse X-ray scattering, and the effect of piezo-electricity is particularly noted. The calculations of the average temperature parameters along the a- and the b-axis respectively are B^P_<11>=0.69 and B^P_<33>=0.20 (in Å^2 units) in the unclamped case and B^E_<11>=0.72 and B^E_<33>=0.29 in the clamped case. These results are then compared with previous experimental results from X-ray (Evans) and neutron diffraction (Frazer).
