Question Adding data to the neutronHP libraries 

Forum: Hadronic Processes
Date: 25 Feb, 2010
From: Mario <Mario>

I am currently running Geant4.9.3 (previously used 4.9.0) and wrote a simple simulations to look at recoil protons and alphas from fusion neutrons (<~14-MeV) so I thought I should use the *HP physics list (currently using QGSP_BERT_HP).

I finally got everything up and running only to find out that one of the few materials, Tantalum-181 I would be using is not in the G4NDL3.13 Inelastic or Elastic folders... there is however something for Ta-181 in the JENDL_HE folder (not sure what the energy threshold is for these data files).

I have looked up some of the ENDF-6 XS files to see if there was a simple correlation between the format of the ENDF-6 files and the data files in G4NDL3.13. I did not see anything obvious.

Is there a way that I can generate a data file for Geant4 from an ENDF-6 file from NNDC, put it in the correct folder under G4NDL3.13/Inelastic or Elastic, and therefore not use the Tungsten XS for the Tantalum material?

Or is there a way to make neutronHP use the file from JENDL_HE if in the proper energy range?

Thanks in advance!! Mario
