Hi, I am trying to follow the polarization of protons traversing an (unpolarized) carbon target, however this looks harder than expected. Any tip would be very appreciated. I wouldn't expect any spin kinematics to change in the current implementation of hadron processes (or do they?). But I'd expect that at least EM scatterings will change the proton's spin vector. However, I never see it changing no matter the kind of interaction. Moreover, I generate protons with polarization (0,1,0) and when I do the following as a test, postStepPoint->AddPolarization(G4ThreeVector(0.01,0.,0.)) , I see the addition taking place only at exactly the second step of the trajectory. Could you please let me know if all this is expected or if it rings a bell of some omission in my code? Best regards Eleni
