WHAT FOR ?
I - ORIGIN of DATA SENT FOR COMPARISON
II - FWHM ESTIMATIONS
III - RESULTS
A) CeO2 and m-ZrO2 data treated with FULLPROF in Fobs extracting mode:
B) For memory, the results posted originally to sci_tech_xtal:
C) From posts of Cline and Kaduk using GSAS on LaB6 SRM 660:
IV - CONCLUSIONS
> 1- One can hear sometimes that variable slits lead to irreproducible
> measurements, is that true ?
> 2- Has anybody better results with an in-laboratory apparatus (eventually
> Kalpha1) on both aspects (FWHM and Rp) for these well known standards ?
