Hi,
There is a new version of GSAS for Windows. The Linux one will be out in a bit. Below
are lines from GSASNEWS.TXT with details of the new things & fixes in this version. In
brief, there is now conjugate gradient refinement, new tables of f' & f" for 10
standard wavelengths (CoKa fans can no
My posting provoked the kind of response that I had hoped for.
First, let me apologize for being Americo-centric. It is an easy trap to
fall into.
My concern is not about the lack of brain power, only the way it is
supported. For example, I have worked on a joint project with Martin
Kroeker
Hi,
According to GSASNEWS.TXT from July 6,1999.
"19. RAWPLOT now has the option for fitting positions, areas & shapes of up
to 30 individual reflections in a powder pattern using the same profile functions
available in GENLES."
GSASNEWS.TXT is part of the standard GSAS distribution and is in th
Dears all,
Can anybody help me to convert B1a1(non-standard
setting) into P1c1 (standard setting)?
"According to A. D. Rae's report which is appeared in
Acta Cryst. (1990), B46, 474-487,
B1a1 can be transformed to P1c1 using new axes
(a+c)/2, b, c and origin relocated to put the glide at
y=0."

Hi,
May I ask what is the exact formula used
by rawplot refinement? There are 6 parameters: pos, int, alp, bet, sig,
gam, what are their meanings? If i want to compare the changes of a peak at
different banks or different temperature, what is the most important
parameter?
Thanks:)

Hi!
I want to do rietveld analysis of the alloy Zr 2.5% Nb.
Can anybody tell me how to incorporate the phase,occupation etc. in the rietveld
analysis for the alloy system.
Thanking you.

Try the "Explore symmetry" tool @:

You'll need to use P63/m m c and P63/m c m Without the / the symbol is
wrong.

It is the orientation of the m mirror axis and the c glide planes with
respect to the
"Blickrichtungen", directions of view, which are defined differently for
each crystal system. For the hexagonal one the first one is [001], the
second one is [100], the third one [120].

Dear all Rietcelder,
Can anyboby tell me the difference between these two space groups?
P63m m c and P63m c m?
many thanks,
