Good Idea!
Size-Strain Round Robin results for CO2 sample
Method: Rietveld-refinement using Modified Thompson-Cox-Hastings
profile function with the Gaussian and Lorentzian FWHM defined as:
FWHMG = (Utan2q + Vtanq + Z/cosq2 + W)1/2
FWHML = X tanq + Y/cosq
Computer Program: Local modification of DBWS
Results of fitting data from the University of Le Mans
"Instrumental standard":
X = 0.0379(8), Y = 0.0116(7), W = 0.00152(5), U=V=Z=0
R-factors: Rwp = 0.110, Rp = 0.074, RB = 0.012
"Broadened sample":
X = 0.080(2), Y = 0.149(2), Z = 0.0396(7), W = 0.00152, U=V=0
R-factors: Rwp = 0.069, Rp = 0.050, RB = 0.036
Calculated volume-weighted size Dv = 273 Å
