42 // e-/e+ Coulomb scattering model based on num
43 // (DCS) obtained by Dirac Partial Wave Analys
44 // G4eDPWAElasticDCS class.
45 // The model contains the possibility to incor
46 // deflections of sub-threshold ionisation int
47 // the condensed history model. Note, this mus
48 // `isscpcor` input argument of the CTR to fal
49 // with a classical, event by event based simu
50 // condensed history approach (otherwise, the
51 // will be "double counted").
