/* */

TGeoMaterial()
 Default constructor

TGeoMaterial(const char *name) :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

TGeoMaterial(const char *name, TGeoElement *elem, 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
