Question charge exchange model for proton induced spallation 

Forum: Hadronic Processes
Date: 01 Sep, 2015
From: Cristian Bungau <Cristian Bungau>

Dear all,

I came across few months ago a paper describing how well the charge exchange model in Geant4 describes the low energy (35 MeV) proton induced spallation in Beryllium, when coupled with Binary cascade - Nuclear Instruments and Methods in Physics Research B 342 (2015) 194199.

Since then I have tried without success to reproduce the results shown in that paper and I had no luck in getting in touch with the authors. The way I activate the CE model is simply like this:

         G4ChargeExchange * theCEModel = new G4ChargeExchange;
         theCEModel->SetMinEnergy( 0.*MeV ); 
         theCEModel->SetMaxEnergy( 200.*MeV ); // not relevant here (35 MeV projectiles)
         theInelasticProcess->RegisterMe( theCEModel );

and as you can see, I do not associate any cross-sections to it (the hadronic models verbose 1 summary shows that the model is using the Gheisha inelastic cross-sections), but the results are quite different from those shown in the NIM published paper.

I would be very grateful if you could please let me know if there is any other/proper way to activate this model and what are the corresponding cross-sections which I should use for these spallation processes (if any of course), so I can add them to my PhysicsList.

Thank you for your help,

Best regards,

Cristian Bungau
