Member Function Documentation

template<typename generator_t >

double ActsFatras::detail::GaussianMixture::operator() ( generator_t &  generator, const Acts::MaterialSlab &  slab, Particle &  particle  ) const

inline

Generate a single 3D scattering angle.

Parameters

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

Returns

a 3d scattering angle

Template Parameters

generator_t

is a RandomNumberEngine

Calculate the highland formula first
