I’m trying to calculate the positron range of F18 in water. There are three examples provided with the installation files, which I think are directly related to this problem. They use different physics lists, and I wonder which one is most suitable for F18.
-
The example ‘\basic\B3’ uses G4DecayPhysics, G4EmStandardPhysics, and G4RadioactiveDecayPhysics.
-
The example ‘\extended\radioactivedecay\rdecay01’ uses G4Radioactivation.
-
The example ‘\extended\radioactivedecay\rdecay02’ uses G4EmStandardPhysics, G4DecayPhysics, BiasedRDPhysics, G4HadronElasticPhysics, G4HadronPhysicsFTFP_BERT, G4IonElasticPhysics, G4IonPhysics, G4EmExtraPhysics.
2 uses only G4Radioactivation, so I assume it’s least accurate. 1 directly addresses the F18 simulation and it uses only three physics lists, so I assume it may be the optimal choice in terms of both computation time and accuracy. However, setting aside the computation time, would 3 provide the highest accuracy as it uses more physics lists than the others?
