Hi All, I am trying to fit a large unknown amorphous phase. It is not being properly fit by my background and being fit by broadening out the peaks of other small phases present that should be crystalline. I did XRD-CT on a lead pipe scale material and so I cannot spike the sample with a known weight percentage of material with a similar absorption coefficient. Is there any way that I can fit this unknown phase as just a general unknown amorphous material and exclude it from the weight percent calculation?
Thanks, Claire
