Comparison of FENDL3.2b with FENDL2.0 for select isotopes and reactions. #70

Open eitan-weinstein opened 3 months ago

eitan-weinstein commented 3 months ago

Includes a python script that processes cross section data from FENDL3.2b and FENDL2.0 for a specific isotope and reaction to plot the cross sections over each other against the 175 energy groups in the Vitamin-J structure. Additionally, a number of example cases are included.

I wonder if @bohmt has any thoughts on these cross-section comparison plots?

@gonuke, and @eitan-weinstein, you may have discussed this while I was out, but I'm not a fan of adding nuclear data and plots (binary data) to git due to bloating the repo, and the principle of git is for "inputs" not "outputs".

As for the plots:

  1. Could you export as svg so that way we can zoom in with vector graphics?
  2. Some of these (specifically Co-59 (n,g)) look "out of phase". Are you using energy bin edges consistently for plotting (i.e., lower, upper, middle)? Or did they change the nuclear data? I think checking the resonance parameters would be a quick check of that. I don't remember where those are stored though. I feel like it would MF=1 though.
