Detailed Description

Common electromagnetic physics parameters (see G4EmParameters.hh).

Note: Geant4 v11 removed the Spline() option from G4EmParameters.hh.; The Geant4 MSC models use the values in G4EmParameters as the defaults; however, the MSC parameters can also be set directly using the model setter methods (there is no way to retrieve the values from the model in that case).

The documentation for this struct was generated from the following file:
