Hi, I’m trying to simulation the a CLYC thermal neutron detector with text geometry. I define Li6 and Li7 like this, with 0.1eV neutron, and physics list QGSP_BERT_HP.
:ISOT Li6 3 3 6
:ISOT Li7 3 4 7
I believe this is right according to https://geant4.web.cern.ch/collaboration/working_groups/persistency/docs/textgeom.pdf, which tell me the syntax is :ISOT NAME Z N A
.
But warinings for wrong isotope Li3, Li4 were shown.
NeutronHP: /Elastic file for Z = 3, A = 3 is not found and NeutronHP will use /home/wqd/soft/geant4/geant4-v11.2.2-install/share/Geant4/data/G4NDL4.7.1/Elastic/CrossSection/3_6_Lithium
NeutronHP: /Elastic file for Z = 3, A = 4 is not found and NeutronHP will use /home/wqd/soft/geant4/geant4-v11.2.2-install/share/Geant4/data/G4NDL4.7.1/Elastic/CrossSection/3_6_Lithium
If I switch the definition to this one, the warning for Li disappeared.
// CLYC
:ISOT Li6 3 6 6
:ISOT Li7 3 7 7
