G4_CESIUM_IODIDE: cesium iodide, an inorganic crystal scintillator with a density of 4.51 g/cm3 and a refractive index of 1.79.

G4_Pb: lead, a high-density and high-Z material that is commonly used as an absorber for electromagnetic calorimeters. It has a density of 11.35 g/cm3 and a radiation length of 0.56 cm.
G4_Fe: iron, a medium-density and medium-Z material that is often used as an absorber for hadronic calorimeters. It has a density of 7.87 g/cm3 and an interaction length of 16.77 cm.
G4_W: tungsten, a very high-density and very high-Z material that is suitable for compact and high-resolution electromagnetic calorimeters. It has a density of 19.3 g/cm3 and a radiation length of 0.35 cm.
G4_Cu: copper, a high-density and high-Z material that is also used as an absorber for electromagnetic calorimeters. It has a density of 8.96 g/cm3 and a radiation length of 1.43 cm.

G4_PbWO4: lead tungstate (CMS ECAL). Lead tungstate has a very high density of 19.3 g/cm3 and a very short radiation length of 0.35 cm, which makes it suitable for compact and high-resolution electromagnetic calorimeters
