Abstract

In this study, the photon interaction and the electron nonproportional response of Cs₂LiYCl₆:Ce (CLYC) scintillation were studied. The radioactive source of ¹³⁷Cs that irradiated gamma rays with an energy of 662 keV were used in this experiment. For photon interaction, the mass attenuation coefficient (μ/ρ), the effective atomic number (Z_eff) and the electron density (N_el) were measured with eight different gamma ray energies using Compton scattering technique. For nonproportional response, the coincidence electron energy spectra were recorded at seven scattering angles of 30°–120° using Compton coincidence technique. The values of μ/ρ, Z_eff and N_el show decrease with the increasing of gamma ray energies. The nonproportional show that the CLYC demonstrated good proportional property all in the electron energy range of 99.24–450.59 keV.
