Bremsstrahlung data set is loaded incorrectly. It causes wrong shape of spectrum.. To fix it is easy, replace line 213 of G4BremsstrahlungParameters.cc as below: -- if(!used) { ++ else{
Thanks for spotting the problem. The fix will be publicly available in Geant4 public release 5.0, to be distributed on 13 December 2002. Best regards, Maria Grazia Pia
