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.
