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.

This performs the same sampling as in Geant4's G4eCoulombScatteringModel, as documented in [g4prm] (release 11.1, section 8.2).

Todo:

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