Detailed Description

Perform Moller (e-e-) and Bhabha (e+e-) scattering.

This interaction, part of the ionization process, is when an incident electron or positron ejects an electron from the surrounding matter.

Note

This performs the same sampling routine as in Geant4's G4MollerBhabhaModel class, as documented in section 10.1.4 of the Geant4 Physics Reference (release 10.6).

Constructor & Destructor Documentation

MollerBhabhaInteractor()

CELER_FUNCTION celeritas::MollerBhabhaInteractor::MollerBhabhaInteractor ( MollerBhabhaData const &  shared, ParticleTrackView const &  particle, CutoffView const &  cutoffs, Real3 const &  inc_direction, StackAllocator< Secondary > &  allocate  )

inline

Construct with shared and state data.

The incident particle must be within the model's valid energy range. this must be handled in code before the interactor is constructed.

CELER_FUNCTION Interaction celeritas::MollerBhabhaInteractor::operator() ( Engine &  rng )

inline

Sample e-e- or e+e- scattering using Moller or Bhabha models, depending on the incident particle.

See section 10.1.4 of the Geant4 physics reference manual (release 10.6).

Todo:

Remove and replace with an assertion once material-dependent model bounds are supported
