Detailed Description

Set up and launch the gamma-nuclear model interaction.

The class also builds element cross-section tables using G4PARTICLEXS/gamma (IAEA) data at low energies and CHIPS gamma–nuclear cross sections using G4GammaNuclearXS above the IAEA upper energy limit (~130 MeV). The CHIPS cross sections are based on the parameterization developed by M. V. Kossov (CERN/ITEP Moscow) for the high energy region (106 MeV < E < 50 GeV) and on a Reggeon-based parameterization for the ultra high energy region (E > 50 GeV), as described in degtyarenko-chiralinvariant-2000. G4GammaNuclearXS uses CHIPS (G4PhotoNuclearCrossSection) above 150 MeV and performs linear interpolation between the upper limit of the G4PARTICLEXS gamma-nuclear (IAEA) data and 150 MeV.
