[Gate-users] Defining a pure alpha source with Gate?

Hi everyone,

I know it is possible to define a beta/gamma source with Gate, using 
UserSpectrum and the "/gate/source/spectrumname/gps/particle beta" 
command, for example. Is it possible to do this with alpha particles as 
well? There is nothing in the documentation about it, but I think Geant4 
is capable of doing things like that, so I was wondering if there was a 

Similarly, it is possible to use the "ion source" for an alpha emitting 
isotope, but tell Gate to not simulate gammas/betas/anything besides 

Thank you!
