Figure 6
Measured FWHMs versus 2θ of LaB6 (NIST SRM660b) for different detector distances (D0 = 40, 50, 70 and 90 cm). (a) 0.5 mm capillary with Ge(111) monochromator and (b) 0.5 mm capillary with Mo Kα1,2 radiation. Results of least-squares fits of the Caglioti formula to the FWHM of the LaB6 reflections are also included as dashed lines. |
