Common electromagnetic physics parameters (see G4EmParameters.hh).
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). | MscStepLimitAlgorithm celeritas::ImportEmParameters::msc_muhad_step_algorithm |
MSC step limit algorithm for muon/hadron.
