Forum: Physics List
Re: Question problems about "QGSP_BIC_HP"and several questions (Geng)
Date: 19 Sep, 2012
From: <matthieu>

I'll try to answer this in case someone stumble upon this thread like I did...

------------------------------------------------------------------------------------------------------------------------------------
(1) 
I want to simulate dosimetry of neutron(0-100M) / proton (GeV)/heavy ions (GeV)
   So like these situations, which physics list you suggest to me?
---> Below 20 GeV QGSP_BIC_HP is a good choice.
------------------------------------------------------------------------------------------------------------------------------

------------------------------------------------------------------------------------------------------------------------------
   (2) When I use “runManager->SetUserInitialization(new QGSP_BIC_HP)”in main(),
Errors occurs like“
NeutronHP: /Capture file for Z = 8, A = 18 is not found and NeutronHP will use /u/ey/perl/geant4/geant4.9.4/data/G4NDL3.14/Capture//CrossSection/8_17_Oxygen
NeutronHP: /Elastic file for Z = 8, A = 18 is not found and NeutronHP will use /u/ey/perl/geant4/geant4.9.4/data/G4NDL3.14/Elastic//CrossSection/8_17_Oxygen
NeutronHP: /Inelastic file for Z = 8, A = 18 is not found and NeutronHP will use /u/ey/perl/geant4/geant4.9.4/data/G4NDL3.14/Inelastic//CrossSection/8_17_Oxygen
NeutronHP: /Capture/ file for Z = 8, A = 18 is not found and NeutronHP will use /u/ey/perl/geant4/geant4.9.4/data/G4NDL3.14/Capture///CrossSection/8_17_Oxygen
”
---> I get the same errors with QGSP_BIC_HP 1.3 [in main like you did with runManager->SetUserInitialization(new QGSP_BIC_HP)], and apparently that doesn't
matter as geant4 will use another file to get the cross sections, e.g. see my output:
