Question access to cross section values

Hi,

maybe someone of you has a clever idea solving the following problem I currently stuck with:

During the simulation I need to get NIST like information about the different cross section values for:

  * a given (previously introduced) material
  * a specific particle type
  * a specific process (previously assigned to this particle)

Although Geant4 permanently has to handle this data for particle tracking I could not find a method to get access to it. All I saw up to now is, that each process provides a methode called 'GetMeanFreePath(...)' which requires a valid G4Track handle. Unfortunately, every time I create and pass an 'artificial' G4Track object to this methode, I get a segmentation violation for unknown reasons. Any idea?

Thanks in advance!

Regards Andy
