Detailed Description

Applies the Wentzel single Coulomb scattering model.

This models incident high-energy electrons and positrons elastically scattering off of nuclei and atomic electrons. Scattering off of the nucleus versus electrons is randomly sampled based on the relative cross-sections (see celeritas::WentzelHelper). Production cuts are used to determine the maximum scattering angle off of electrons.

Note

This performs the same sampling as in Geant4's G4eCoulombScatteringModel, as documented in section 8.2 of the Geant4 Physics Reference Manual (release 11.1).

Todo:

When hadronic EM processes are supported, this should be extended to emit secondary ions.
