Hi Michael,
It is best to start by guessing the third cumulant only, leaving the fourth
cumulant set to zero. A survey of the published literature shows very few
examples where the fourth cumulant has been fit--by that point the cumulant
expansion itself is starting to become iffy, which is not
Michael,
The values for C3 and C4 should be very small -- they are in Ang^3 and
Ang^4, and should be numerically smaller than sigma2 (in Ang^2). I would
expect values of 0.001 for C3 in a highly disordered system. I'm not sure
anyone has actually seen a value for C4 that was not consistent wit
Hello,
I'm trying to make an EXAFS analysis on the Structure of Tb in a
borogermanate glass System. The reference is an .cif of
Terbium-Gallium-Garnet (TGG).
I expect some disorder caused to working in glass. Therefore I would
like to use the 3rd and/or the 4th parameter. I tried to set a gu
