Sorry, pressed the wrong button...
If you just want to try fitting the peaks, you could try something like this:
str
phase_name "Metal_oxide"
local broad 100 'crys size for hk0 and hkl
local sharp 2000 'crys size for 00l
local csL =
IF (And(H == 0,
In response to the question posted this morning by Frank Girgsdies:
Here is a little snatch of topas code for anisotropic broadening in
orthorhombic system. (The fitted parameters come from a particular
refinement I took this from; the factor of 10^4 is empirically chosen to
get parameter valu

A quick query for people
A few of the ICSD crystal structure entries (such as [Metathenardite]
Disodium sulfate(VI)) have references to:
Golden Book of Phase Transitions, Wroclaw (2002)
Does anyone know if this book really exists and where it can be
obtained from? Even http://www.abebooks.
Dear Frank,
I don’t have an exact recipe for Topas, but a general consideration of the
problem you face with may be found in J. Appl. Cryst. (2008) 615–627. If you
read the paper don’t miss the last sentence of the Conclusions :)

Leonid
Dear Topas experts,
this is my first email to the list, so if you would like
to know something about my background, please refer to
the "about me" section at the end of this mail.
My question is concerning advanced modeling of anisotropic
peak broadening with Alan Coelhos program "Topas".

hi all,
not only fibre like, but single component fibre, and with the fibre axis
parrallel to the sample normal (i.e. "cyclic fibre". this is very
restrictive and generally does not correspond to the real texture.
Contrarilly to what has been said here or there, the March-Dollase does
not ensure P

Hi Blaise
In Bragg-Brentano mode, sample spinning does nothin for PO. This is
because the diffraction vector is normal to the sample surface, and
sample spinning rotates along this vector.
That's wrong! As I have already written, the empirical PO corrections
