Flemming is correct, as usual. Dbars are not defined in GEANT. However, knowing how pbars and deuterons behave is enough to get the dbar (very close to) right.

One can certainly define a particle being a anti-deuteron, and one can make it behave properly in regard to multiple scattering, energy loss and tracking - but NOT for hadronic integraction (and absorbtion) which requires a proper interface to the tracking part of hadronic interaction. Good but tough problem.
