Class Description

/* */
 Default constructor
TGeoMixture(const char *name, Int_t /*nel*/, Double_t rho)
TGeoMixture(const TGeoMixture& gm)
copy constructor
TGeoMixture& operator=(const TGeoMixture& gm)
assignment operator
void AverageProperties()
 Compute effective A/Z and radiation length
void AddElement(TGeoMaterial *mat, Double_t weight)
 Define one component of the mixture as an existing material/mixture.
void AddElement(TGeoElement *elem, Double_t weight)
 add an element to the mixture using fraction by weight
void AddElement(TGeoElement *elem, Int_t natoms)
 Add a mixture element by number of atoms in the chemical formula.
void DefineElement(Int_t /*iel*/, Int_t z, Int_t natoms)
 Define the mixture element at index iel by number of atoms in the chemical formula.
TGeoElement * GetElement(Int_t i)
 Retreive the pointer to the element corresponding to component I.
Bool_t IsEq(const TGeoMaterial *other)
 Return true if the other material has the same physical properties
void Print(const Option_t * /*option*/)
 print characteristics of this material
void SavePrimitive(ostream &out, Option_t * /*option*/ /*= ""*/)
 Save a primitive as a C++ statement(s) on output stream "out".
TGeoMaterial * DecayMaterial(Double_t time, Double_t precision)
 Create the mixture representing the decay product of this material at a
 given time. The precision represent the minimum cumulative branching ratio for 
 which decay products are still taken into account.
void FillMaterialEvolution(TObjArray *population, Double_t precision)
 Fills a user array with all the elements deriving from the possible
 decay of the top elements composing the mixture. Each element contained
 by <population> may be a radionuclide having a Bateman solution attached.
 The precision represent the minimum cumulative branching ratio for 
 which decay products are still taken into account.
 To visualize the time evolution of each decay product one can use:
    TGeoElement *elem = population->At(index);
    TGeoElementRN *elemrn = 0;
    if (elem->IsRadioNuclide()) elemrn = (TGeoElementRN*)elem;
 One can get Ni/N1(t=0) at any moment of time. Ni is the number of atoms
 of one of the decay products, N1(0) is the number of atoms of the first top
 element at t=0.
    Double_t fraction_weight = elemrn->Ratio()->Concentration(time);
 One can also display the time evolution of the fractional weigth:
void DefineElement(Int_t, Double_t a, Double_t z, Double_t weight)
{return AddElement(a,z,weight);}
void DefineElement(Int_t, TGeoElement *elem, Double_t weight)
{return AddElement(elem,weight);}
Int_t GetByteCount()
 getters & setters
{return sizeof(this);}
Bool_t IsMixture()
{return kFALSE;}
void AddElement(Double_t a, Double_t z, Double_t weight)
 methods for adding elements
Int_t GetNelements()
{return fNelements;}
Double_t * GetZmixt()
{return fZmixture;}
Double_t * GetAmixt()
{return fAmixture;}
Double_t * GetWmixt()
{return fWeights;}
Int_t * GetNmixt()
{return fNatoms;}
void SetA(Double_t a)
{fA = a;}
void SetZ(Double_t z)
{fZ = z;}
