◆ bremPhoton()

Particle ActsFatras::BetheHeitler::bremPhoton	(	const Particle &	particle,
		double	gammaE,
		double	rndPsi,
		double	rndTheta1,
		double	rndTheta2,
		double	rndTheta3 ) const

Simulate the photon emission.

Parameters

[in]	particle	The unmodified electron
[in]	gammaE	Energy of the photon
[in]	rndPsi	Random number for the azimuthal angle
[in]	rndTheta1	Random number for the polar angle
[in]	rndTheta2	Random number for the polar angle
[in]	rndTheta3	Random number for the polar angle

Returns: Particle representing the emitted photon

◆ operator()()

template<typename generator_t>

std::array< Particle, 1 > ActsFatras::BetheHeitler::operator()	(	generator_t &	generator,
		const Acts::MaterialSlab &	slab,
		Particle &	particle ) const

Simulate energy loss and update the particle parameters.

Parameters

[in]	generator	is the random number generator
[in]	slab	defines the passed material
[in,out]	particle	is the particle being updated

Returns: Produced photon.

Template Parameters

generator_t is a RandomNumberEngine
