Re: Question Does GEANT4 simulated (alpha,n) reactions? (Daniel Cano Ott)
Date: 25 Jun, 2008
From: Daniel Cano Ott <Daniel Cano Ott>

Thanks for your quick reply.
No, I did not try. Could you please be so kind and let me know where 
could I download it? Furthermore, isn't there a table based production 
physics list like for the neutrons? Models are nice at high energies but 
shall have a poor performance at low energies (i.e. below 20 MeV).

Thanks a lot in advance,

Daniel
