Hi, ROOT team, Is it possible to implement GEANT-3 GSMIXT() NLMAT-like option in TGeoMixture? -----------------from GEANT-3 doc-----------> CALL GSMIXT (IMATE,NAMATE,A,Z,DENS,NLMAT,WMAT*) ... NLMAT - number of elements in the mixture; > 0 WMAT contains the proportion by weights of each material in the mixture; < 0 WMAT contains the proportion by number of atoms of each kind, the content of WMAT in output is changed to contain the relative weights; -----------------from GEANT-3 doc-----------> I think it will be suitable to define materials according to its chemical formulas like: TGeoElement* O = new TGeoElement ("O","Oxygen",15.9994,8,); TGeoElement* C = new TGeoElement ("C","Carbon",12.0107,6,); TGeoElement* H = new TGeoElement ("H","Hydrogen",1.00794,1); // Mylar wrapper C10H8O4 TGeoMixture *mat4 = new TGeoMixture("MYLAR",3,dmyl); mat4->SetUniqueID( 4); mat4->DefineElement(C,-10.); mat4->DefineElement(H,-8.); mat4->DefineElement(O,-4.); Best, Yuri
