Question how can I tell if LENDL is being used by Geant4? 

Forum: Physics List

From: John McFee <John McFee>

I am modeling photoneutron reactions at low energy (<20 MeV incident gamma rays) using Geant4 10.4 patch 01. I am presently using the QGSP_BERT_HP reference physics list, but I want to ensure that the G4LEND data is being used. (Am I correct in assuming that QGSP_BERT_HP will use it can find it?) I downloaded the LEND_GND1.3_ENDF.BVII.1 data package, unzipped it and I have the G4LENDDATA environment variable pointing to its location (I checked). I have NOT recompiled Geant4. How can I tell if LENDL is being used? When I run my code verbosely, I get this output, but that does not answer my question:

			Hadronic Processes for gamma
Process: photonNuclear
        Model:            BertiniCascade: 0 eV  ---> 3.5 GeV
        Model:           TheoFSGenerator: 3 GeV ---> 100 TeV
     Cr_sctns:            PhotoNuclearXS: 0 eV  ---> 100 TeV
     Cr_sctns:            GheishaInelastic: 0 eV  ---> 100 TeV

There may be clear documentation on how to do this, but I cannot find it in the Guide for Physics Lists, Physics Reference Manual or Book For Application Developers. Thank you for your help.
