The problem of getting ion particles

When I use the function GetIon(G4int encoding), I noticed that some ion particles can be created but will not be simulated. For example, Ge94(not exist in the real world) with pdgcode 1000320940 can be
created by the function, but it wil not deposit energy.

So, Can I have some method to make the particles deposit energy like those normal particles? Or if the particle will not work, can I know by some functions?
