Hi Peter, thanks a lot for the quick reply,

Please do not, it was only a test to see if the polarization interacts at all. 


After what you said, I'd like to see if my understanding about the polarization 
of massive particles in G4 is correct: 

In the presence of external e/m fields, a particle's spin precesses as expected. 
In decays, the polarization is taken into account for the kinematics of the 
decay products. 
Scatterings of any kind do not affect the spin vector. 

Is this right? 

Thanks, 
Eleni
