Question GEANT4 - G4NDL4.2 Cross Sections 

Forum: Hadronic Processes
Date: 13 Mar, 2017
From: <marchick>

Hello,

I would like to update the cross sections, specifically those for Ar40, to ENDF/B-VII.1, as ENDF/B-VI (what GEANT4 appears to be using?) is missing some some small but important features in the capture and inelastic cross sections that I wish to add. It may be that my collaboration is using an outdated version, but I only wish to do a local update for this group.

The question I have for you is: when I look at, say, the 18_40_Argon inelastic cross section file, I see there are three numbers above the energy and corresponding cross section table. Would you be able to clarify what they represent? The three numbers and first row of E->xs are given below.

Thanks, Bryce
