How to simulate heavy ion as incident particles?

I want to simulate a 500MeV Be9 beam. I have tried

G4IonTable::GetIonTable()->GetIon(4,9,0);

But it seems doesn’t work properly.
Is there any examples or instructions about this?

That should be exactly right. However, you can only make that call after the RunManager has been initialized (e.g., the /run/initialize macro command). If you have your own PrimaryGeneratorAction, move that call to the GeneratePrimaries() function.
