Detailed Description

The manager class for accessing hadronic cross sections.

The main methods:

The selection of the particle, the element and the histogram parameters (energy and moment range and number of bins) has to be done first via the set methods of the class.

In MakeHistograms(), the array with the following histograms for the selected parameters is filled and returned:

  • Elastic cross section (barn) as a functions of log10(p/GeV)
  • Elastic cross section (barn) as a functions of log10(E/MeV)
  • Inelastic cross section (barn) as a functions of log10(p/GeV)
  • Inelastic cross section (barn) as a functions of log10(E/MeV)
  • Capture cross section (barn) as a functions of log10(E/MeV)
  • Fission cross section (barn) as a functions of log10(E/MeV)
  • Charge exchange cross section (barn) as a functions of log10(E/MeV) (inactivated)

If verbose level is set >=1 then a table with cross section values per energy values is printed.

It is also possible to access the cross section value for a selected energy or a momentum via GetCrossSection() method. A selected cross section or all cross sections can be also printed via PrintCrossSection[s] methods.

Implemented according to the Geant4 example: extended/hadronic/Hadr00.
