A study of light quenching in BaF2 crystals for heavy ions at intermediate energies

Abstract The light response of BaF 2 crystals to light and heavy ions (1 ≤ Z ≤ 15) has been investigated as a function of energy, charge and mass of the incident particles up to ∼ 40 A MeV. While it is possible to describe the light output using a unique function of E , Z and A for all the ions, the Birks' constant seems to depend on the charge of the incident ion. Only a small dependence on the mass of the detected ion is found.
