Particle bremPhoton(const Particle &particle, Scalar gammaE, Scalar rndPsi, Scalar rndTheta1, Scalar rndTheta2, Scalar rndTheta3) const¶
Simulate the photon emission.
- Parameters
particle – [in] The unmodified electron
gammaE – [in] Energy of the photon
rndPsi – [in] Random number for the azimuthal angle
rndTheta1 – [in] Random number for the polar angle
rndTheta2 – [in] Random number for the polar angle
rndTheta3 – [in] Random number for the polar angle
-
template<typename generator_t>
inline std::array<Particle, 1> operator()(generator_t &generator, const Acts::MaterialSlab &slab, Particle &particle) const¶ Simulate energy loss and update the particle parameters.
- Parameters
generator – [in] is the random number generator
slab – [in] defines the passed material
particle – [inout] is the particle being updated
- Template Parameters
generator_t – is a RandomNumberEngine
- Returns
Produced photon.
