36 // Description: This class is similar to G4UnknownParticle,
37 // i.e. representing particles with valid PDG code but
38 // unknown to Geant4 - e.g. produced by MC event
39 // generators - but with the extra requirement of having
40 // a non-zero electric charge.
41 // While for G4UnknownParticle is possible to assign
42 // transportation and decay processes, for
43 // G4ChargedUnknownParticle is also possible to assign
44 // ionisation and multiple scattering.
45 //
