Question Geant4 for prompt gamma neutron activation analysis (PGAA) 

Forum: Physics List
Date: 12 Feb, 2018
From: Sakari Ihantola <Sakari Ihantola>

I am trying to use Geant4 to study prompt gamma neutron activation analysis (PGAA). For this study, it would be crucial to properly simulate the gamma-rays produced in absorption of thermal neutrons in Cd-113 and Gd-157.

Unfortunately, the G4NDL library (and the ENDF library that it is based on) does not seem to contain the energies of the gamma rays produced in Cd-133. For Gd-157, the gamma spectrum given is a continuum that does not contain the characteristic peaks that are essential for isotope identification in PGAA.

My question is, what would be the best way forward? The characteristic gamma energies are reported, for example, in JEFF-3.3 data library that is in ENDF-6 format. However, converting this data into an undocumented G4NDL format sounds quite difficult. Another option would be to convert the JEFF-3.3 files into GND format (https://ndclx4.bnl.gov/gf/project/gnd/) with Fudge and read the data into Geant4 with G4LEND. However, I am a bit sceptic if this would actually work.

All suggestions and comments are very welcome!
