Class Description

 Particle definition, partly based on GEANT3 particle definition      

  Particle definition default constructor

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, Double_t LowerCutOff, Double_t HighCutOff) : TNamed(name,title)
  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.

  Particle destructor

Int_t ConvertISAtoPDG(Int_t isaNumber)
  Converts the ISAJET Particle number into the PDG MC number

void DefinePDG()
  Defines particles according to the Particle Data Group

  For questions regarding distribution or content of the MC particle
  codes, contact
  Gary Wagman (GSWagman@LBL.BITNET, LBL::GSWagman, or GSWagman@LBL.GOV).

TAttParticle* GetParticle(const char *name)
  Get a pointer to the particle object according to the name given

TAttParticle* GetParticle(Int_t mcnumber)
  Get a pointer to the particle object according to the MC code number

void Print(Option_t *) const
  Print the entire information of this kind of particle

Double_t SampleMass() const
  Samples a mass according to the Breit-Wigner resonance distribution

Double_t SampleMass(Double_t widthcut) const
  Samples a mass in the interval:

  fPDGMass-widthcut*fPDGDecayWidtht - fPDGMass+widthcut*fPDGDecayWidth

  according to the Breit-Wigner resonance distribution
