Dear Geant4 Experts
Thanks you in advance for your considration and time.
I have a question about the subtype number of process which results in production of secondary gamma during interaction of proton with water.
when my physics list is only
/physic/addPhysics standard_opt3 # Electromagnetic model
/physic/addPhysics elastic # Hadronic elastic model
/physic/addPhysics binary # Hadronic inelastic model
/physic/addPhysics radioactive_decay # Radioactive decay
the resposible subtypes for gamma generation are (subtype=3, subtype=5, subtype=121, subtype=131 and subtype=-1)
but when the following model is added
"/physic/addPhysics local_ion_ion_inelastic # Hadronic inelastic model for ions (local physic list)"
to the above mentioned models in proton_therapy macro file, the subtype=-1 does not appear in output.
would you please tell me that which process is for subtype=-1 and is it neccesary to add the model "/physic/addPhysics local_ion_ion_inelastic " in proton interaction in order to simulate the secondary ion produced due to target fragmentation?.
With Best Regards
