Hi Dario,

  I don't think you're doing anything wrong.  The main problem is that the model
was designed for higher energies, so the fact that it works at, say 20 MeV, is
fortuitous. At such energies the cascade stage is skipped and the Bertini version
of precompound and evaporation models take over.  In that case, alpha
emission is rare until about 20 MeV as you have seen.
  You might want to try an alternative precompound model.  You can do this with the lines

G4CascadeInterface* theCascade = new G4CascadeInterface();

theCascade->usePreCompoundDeexcitation();

in your physics list. This invokes the Geant4 standard deexcitation code,

which is slower, but has code dedicated to nuclear breakup and thus may do a better job for you.

Dennis
