Here is the relevant bit from Feff:
https://github.com/xraypy/feff85exafs/blob/master/src/COMMON/setgam.f
Note that that bit in Feff is less sophisticated than you might think.
My memory (Matt or John might remember better) is that Steve Zabinski
(main author of Feff6) "interpolated" those values from the plots in the
K&R paper. This was done with a ruler back in the days before we had
software tools for such chores. I am not saying that the values in
setgam.f are wrong -- just not as precise as you might imagine.
