Dear all,

I've Moved from Geant4.5.2.p02 to Geant4.6.1 and have a problem with cuts.
I used,

  G4double cut = 100.0*eV;
  G4Gamma   ::SetEnergyRange(cut,100*GeV);
  G4Electron::SetEnergyRange(cut,100*GeV);
  G4Positron::SetEnergyRange(cut,100*GeV);

with 

  pmanager->AddDiscreteProcess(new G4LowEnergyRayleigh);
  pmanager->AddDiscreteProcess(new G4LowEnergyCompton);
  pmanager->AddDiscreteProcess(new G4LowEnergyGammaConversion);
  pmanager->AddDiscreteProcess(new G4LowEnergyPhotoElectric);
  .
  .
  loweIon  = new G4LowEnergyIonisation;
  loweBrem = new G4LowEnergyBremsstrahlung;
  MuSc = new G4MultipleScattering;	       
  loweIon->ActivateAuger(true);
  loweIon->ActivateFluorescence(true);
  pmanager->AddProcess(loweIon,-1,2,2);
  pmanager->AddProcess(loweBrem,-1,-1,3); 
  pmanager->AddProcess(MuSc,-1,1,1);

to understand the resulting e- distribution in a gaseous detector,
i.e. including re-absorption of flourescence etc.

Using Geant4.6.1, not having 
static void G4Gamma::SetEnergyRange(cut,100*GeV), how do I apply
SetCutValue(cut,"gamma") to get below the 990 eV production threshold?
All my range cuts gets converted to energies at or above 990 eV!

I would really appreciate some help.

Best Regards
Leif
