Constructor & Destructor Documentation

◆ TAttParticle() [1/2]

TAttParticle::TAttParticle ( )

Particle definition default constructor.

Definition at line 32 of file TAttParticle.cxx.

◆ TAttParticle() [2/2]

TAttParticle::TAttParticle	(	const char *	name,
		const char *	title,
		Double_t	Mass,
		Bool_t	Stable,
		Double_t	DecayWidth,
		Double_t	Charge,
		const char *	Type,
		Int_t	MCnumber,
		Int_t	granularity = `90`,
		Double_t	LowerCutOff = `1.e-5`,
		Double_t	HighCutOff = `1.e4`
	)

Particle definition normal constructor.

If the particle is set to be stable, the decay width parameter does have no meaning and can be set to any value. The parameters granularity, LowerCutOff and HighCutOff are used for the construction of the mean free path look up tables. The granularity will be the number of logwise energy points for which the mean free path will be calculated.
