Why should the distribution of lattice parameters (=strain) in a sample
match the crystallographic symmetry? If the sample has random,

Jon,
I risk a public reply here. One possibility everyone should be open to is that a real
phase change has occured during some experimental manipulation of your sample. Some
phase changes are quite subtle and involve only slight (and at first sight) quite odd
line broadening. Higher resolution
Dear Bob and Jon,
one reply from the public is: come to share your and to get other ideas
to the meeting Size-Strain IV (http://www.xray.cz/s-s4/), a satelite
workshop of the EPDIC-9 (http://www.xray.cz/epdic/), end of this summer
in Prague.
The thinks can be even more complex: The
Hi,
I am new to GSAS.I am facing some basic problem and I am confused.
# I am using XRD data from Philips PW 1710 machine.How should I prepare the instrument
parameter file?
#Trying the examples I sometimes fond the option Refine POLA and sometime it was
missing.Why it is so?
Please help me.
Apu,
1. For now use the inst_xry.prm file in \gsas\examples.
2. POLA is appropriate only for X-ray data not neutron data. GSAS knows the
difference.

Hi Dear all,
PDFgetX2 is a GUI driven program to obtain the total-scattering
structure function S(Q) and the pair distribution function (PDF), G(r),
from X-ray powder diffraction data. Its first beta release is available at
