Dear François,
I can think of no reason for a correlation between your peak shape and your
resultant amorphous content, unless somehow the super-Lorentzian peak shape is
not providing accurate intensities. Have you tried your fit with another peak
shape or a fundamental parameters approach? I a
Hi Shay,
I echo some of the other comments. A few other things: Learn how alignment will
be performed (e.g., is it a black-box arrangement?) and how well you can
produce close to 0.000 zero error. Is an independent water chiller required?
How expensive and available are replacement X-ray tubes?
Hello Shay,
I think it is probably related to "tube tails". You can read about this in the
literature (e.g., on the BGMN web site) and you can model it in some Rietveld
software such as Topas. You don't normally notice this but it becomes apparent
with higher-intensity peaks.
Regards,
Dave
The contribution from K-beta (and any other "extra" radiations, e.g., W) can
and should always be modeled.
