Hi all,
I would like to ask if anyone can suggest how to combine synchrotron Voigt profile and anisotropic hkl size broadening - spherical harmonics.
Voigt profile as taken from John Evans' Rietveld module:
prm pr1 0.00676` min 0
prm pr2 0.00682` min 0
prm pr3 0.00731` min 0
prm pr4 0.00809` min 0
lor_fwhm = pr1 Tan(Th) + pr2/Cos(Th) ;
gauss_fwhm = pr3 Tan(Th) + pr4/Cos(Th) ;
anisotropic hkl size broadening - spherical harmonics
prm p10 0.03231` min 0
prm p20 0.03131` min 0
spherical_harmonics_hkl sh
sh_order 6
lor_fwhm = sh p10;
gauss_fwhm = sh p20;
Thank you in advance.
Regards,
Stevin
