Figure 2.10.9

A rocking curve (ϕ scan) of (Ba0.7Sr1.3)TiO4, with the detector fixed at 9.647° 2θ, the top of a strong peak in the synchrotron pattern. The jagged plot is from a static specimen, and shows individual grains moving in and out of diffracting position. The flat curve is from a rotating specimen, and indicates that a powder average was obtained.
