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 (), the effective atomic number () and the electron density () 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 , and 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.
