Constructor & Destructor Documentation

Smear::Bremsstrahlung::Bremsstrahlung	(	double	epsilon = 0.01,
		double	traversed = 10.,
		double	radLength = 47.1
	)

Constructor. Photon energies are randomly generated in the range [epsilon, E - epsilon] for particle energy E. traversed is the distance of material through with the particle passes and radLength is the radiation length of that material (both in cm).

Here is the caller graph for this function:

bool Smear::Bremsstrahlung::SetupPDF ( )

protected

Configure the dSigma/dK function, setting the energy range over which to generate photons. The energy range is computed from the energy of the current mParticle. If the resultant energy range is invalid (e.g. max < min) the range is not set and the function returns false.
