             :TNamed(name, "")



 constructor


 TGeoMaterial(const char *name, Double_t a, Double_t z, 
                Double_t rho, Double_t radlen, Double_t intlen)
             :TNamed(name, "")



 constructor

                Double_t rho)
             :TNamed(name, "")



 constructor


 ~TGeoMaterial()



 Destructor


char* GetPointerName() const



 Provide a pointer name containing uid.


void SetRadLen(Double_t radlen, Double_t intlen)



 Set radiation/absorbtion lengths. If the values are negative, their absolute value
 is taken, otherwise radlen is recomputed using G3 formula.


Double_t Coulomb(Double_t z)



 static function
  Compute Coulomb correction for pair production and Brem
  REFERENCE : EGS MANUAL SLAC 210 - UC32 - JUNE 78
                        FORMULA 2.7.17


Bool_t IsEq(const TGeoMaterial *other) const



 return true if the other material has the same physical properties


void Print(const Option_t * /*option*/) const



 print characteristics of this material


void SavePrimitive(ofstream &out, Option_t * /*option*/)



 Save a primitive as a C++ statement(s) on output stream "out".


Int_t GetDefaultColor() const




TGeoElement* GetElement(Int_t) const




Int_t GetIndex()



 Retreive material index in the list of materials


Double_t ScreenFactor(Double_t z)



 static function
  Compute screening factor for pair production and Bremstrahlung
  REFERENCE : EGS MANUAL SLAC 210 - UC32 - JUNE 78
                        FORMULA 2.7.22
