Dear Santosh,
absolutely, the product has a large user base. But let us continue that discussion off-list.
With best regards,

Dear Martijn
Thanks for our reply. I would llike to know 'Does any body is using panalytical Xpert highscore plus for rietveld refinement?' Iam using GSAS.

Dear Santosh,
please note that Philips/PANalytical Soller slits are specified in radians, and not in degrees. I suppose you are using 0.02 radian Soller slits. Needless to say that this will influence your calculations mentioned in your mail.

Iam using 0.02 degree soller slits. accoding to your formula my S/L comes
to be .00035. but this is very less. is that o.k. to start with? generally
people are using .025 in tutorials.

The only real way to fit the Finger, Cox and Jephcoat factors is by
refinement, partly because the formulation is based on a parallel
incident beam. To a first approximation, take the angle of your Soller
slits, which is given in degrees, and convert it to radians by
multiplying by 3.14159/180. Because the sines and tangents of small
angles are the value of the angle in radians, this number will be the
starting value for S/L and H/L. Measure the diffractogram for a standard
sample with a simple pattern (Si for example) for each of the slit
combinations you plan to use, and refine the asymmetry profile
coefficients. The resulting values will be the correct ones for that
slit combination.
