ERDA PhysicsList

Hello Everyone,

I’m trying to simulate an RBS/ERDA experiment using an alfa source (1.454MeV KE). But my PhysicsList doesnt seem quite good because I’m not having Elastic recoils nucleus. I included these Physics:

RegisterPhysics(new G4EmStandardPhysics_option4());

RegisterPhysics(new G4DecayPhysics());

RegisterPhysics(new G4HadronElasticPhysicsHP());

RegisterPhysics(new G4HadronPhysicsFTFP_BERT_HP());

RegisterPhysics(new G4StoppingPhysics());

RegisterPhysics(new G4IonElasticPhysics());

RegisterPhysics(new G4IonBinaryCascadePhysics());

Hope somebody can help me.

Thanks

1- recoil nucleus is done with cut for proton = 0.*mm

see example hadronic/Hadr06/src/PhysicsList.cc

2- Electromagnetic_option4 is very time consuming. Are you sure you need it ?

Hello @maire1,

Thanks for your quick answer, it works.

Kind regards.
