Hello,

assuming that by "9.4.6" you mean Geant4 version 9.6, I would suggest you to use the physics list FTFP_BERT in order to have Fritiof + Precompound (FTFP) for modelling antiproton annihilations at rest, or QGSP_BERT_95 to have instead CHIPS for modelling antiproton annihilations at rest.

These physics lists do not include the Cherenkov process. To include it, together with optical photons and all their associated processes, try the following, in the your main program (e.g. for the case of FTFP_BERT):

  ...
  #include "FTFP_BERT.hh"
  #include "G4OpticalPhysics.hh"
  ...
  FTFP_BERT *thePL = new FTFP_BERT;
  thePL->RegisterPhysics( new G4OpticalPhysics );
  runManager->SetUserInitialization( thePL ); 
  ...

Regards,
         Alberto
