Try to refine absorption correction. I believe one of the function in GSAS is
designed for capillary.

Henry,
Do you have the correct polarization correction (POLA=0.95, IPOL=0) fro synchrotron
radiation? Did you just use the defaults for Uiso (=0.025)? If so that is too high for
something like HfO2 for which UISO might be closer to 0.004. Either of these would do
what you observe.

Dear friends:
I am trying to refine the structure of Yttrium Aluminum Oxide (Y3Al5O12)
YAG but I could not get the atom sites? Could anyone who know this please
friendly tell me?
Thank you.
