None Antideuteron & particle ID of Ions

Hello, I have three questions which you can maybe answer. I'm using GEANT4 for a cosmic ray simulation in Earth's atmosphere. So far I shoot only "normal" particles like protons, electrons oder positrons in the atmosphere, but I want to have a look at ions (alpha, carbon, boron, ...) and antideuteron up to energies of about 100GeV.

 - Could you please help me and tell me how to define an antideuteron? 
   I didn't find anything on this topic...

 - My other question concerns the ions. To store the particle id in a 
   ROOT file I'm using the PDGcode. Is there some kind of integer 
   accessable for ions which defines them in a non-ambigious way?

 - I had some problems with alphas in GEANT4 with higher energies 
   (starting from a few GeV per nucleon). The code crashes with an 
   exception. Do you have an idea how to use light ions with energies 
   up to 100GeV in GEANT4?

Best regards and have a nice weekend, Philip
