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) 194–199.
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,
