Figure 4
Parameter ξ calculated for the ([002 / 00{\overline 2}]) reflections of BaTiO3, the Ti K absorption edge, and the Ti atom displacements in the range of [−1; 1] Å. Real (x axis) and imaginary (y axis) parts of parameter ξ are plotted. The arrow and labels mark Ti atom displacement along the [001] direction in the tetragonal unit cell of BaTiO3.
