초록
BaCl2 crystals were grown by using the Czochralski method, and their scintillation properties were measured. The emission spectrum was located in the range of 370 ~ 450 nm, peaking at about 400 nm. The fluorescence decay time was approximately 75.9 ns for 662 keV γ-rays excitation. The energy resolution was about 24.4 % for 137Cs 662 keV γ-rays, and the α/β ratio to α particles from a 210Po 5.4 MeV was about 0.25.
