Dear All,
I am currently trying to study a sample of Ba2In2O5 (pellet form diameter =
0.9 cm. Density = 6.00 g/cm3) on GPPD at IPNS. So I am dealing with a Time
of Flight neutron powder diffraction data. I use GSAS as the refinement
package.
This is a highly absorbing sample and I understand the arguments for keeping
mu*R < 1 when dealing with CW neutron diffraction experiments. I am not,
however, familiar with the determination of sample absorption using a TOF
instrument and at what "hard values" I should consider that the absorption
is causing a real problem with the corresponding Rietveld refinement.
Any help or input in this matter would be greatly appreciated.
