(a) Ratio of the normalized integrated intensities of the different wavelengths used, showing the effect on the various Bragg reflections. Dashed lines serve to guide the eyes. (b) Fe -edge absorption of the PB sample. The horizontal arrows indicate that two of the wavelengths ( and ) are outside the limits used for this measurement. The vertical arrow shows the position of the other wavelength .
Rietveld refinements of the structure measured at two distinct wavelengths: (a) and (b) . (+) observed, (red line) calculated, (blue line) difference, and (magenta symbol) Bragg reflections. A few selected indexed reflections are indicated.
Rietveld refinements (selected regions) of the structure measured at three distinct wavelengths: (a) , (b) , and (c) . (+) observed, (red line) calculated, (blue line) difference, and (magenta symbol) Bragg reflections. Various selected indexed reflections are indicated.
Integrated intensities, normalized with respect to the (200) one, of the three distinct wavelengths: , , and .
