Dear, Vladimir,

Thank you very much for answering. Well, I was not using default PhysicsLists, I've made up my own. As for antiprotons, defined processes are:

        else if (particleName == "anti_proton")
          {
             pmanager->AddDiscreteProcess(theElasticProcess);

             G4AntiProtonInelasticProcess* theInelasticProcess =
               new G4AntiProtonInelasticProcess();

             G4LEAntiProtonInelastic* theLEInelasticModel =
                    new G4LEAntiProtonInelastic;
             theLEInelasticModel->SetMaxEnergy(20.0*GeV);
             theInelasticProcess->RegisterMe(theLEInelasticModel);

             pmanager->AddDiscreteProcess(theInelasticProcess);

             pmanager->AddRestProcess(new G4AntiProtonAnnihilationAtRest);

             pmanager->AddRestProcess(new G4QCaptureAtRest());
          }

and, of course, EM part:

        pmanager->AddProcess(new G4MultipleScattering(), -1, 1, 1);
        pmanager->AddProcess(new G4hIonisation(), -1, 2, 2);

Or maybe you are suggesting to use another models/processes for antiprotons?

Thank you,

 Kirill Skovpen
