HI Franz,
It seems to me that the best thing would be to use K alpha 1 wavelength (which
is 66 percent of the total intensity) and then mentally ignore the K alpha 2
contribution. The other option is to strip the original data of K alpha 2, if
your diffractometer's software has that option, but since stripping is a kind
of data manipulation, I don't usually like doing it.

Subject: Comparison of powder patterns recorded at different wavelengths
Hello Rietvelders
I want to compare graphically powder patterns of a phase which were recorded at
different wavelengths. Therefore I'd like to overlay the patterns using
d-values, calculated from their corresponding 2theta values. In the case of
monochromatic X-rays it's trivial. But which wavelength should one use in the
case of Kalpha1-Kalpha2 radiation (lab instrument)?
Thanks for your help.
