摘　　要：报道了大面积 BGO闪烁探测器用于 132 Me V16O+ 197Au反应中形成的热核巨共振研究 ,利用飞行时间法鉴别中子、γ。用 EGS4程序模拟探测器对 γ连续谱的响应 ,利用 BGO闪烁探测器中 Ge俘获中子发射的 γ对探测器进行能量刻度。This paper reports two large area BGO scintillator detectors that were successfully used to study the Giant Dipole Resonance (GDR) of hot nuclei. Time of flight was used to separate γ rays from fast neutrons. The energy calibration of the BGO detectors was obtained by using the 7.4 MeV and 10.2 MeV γrays originating from slow neutron capture in Ge isotopes. The EGS4 code was used to simulate the responding of BGO detector to high energyγrays.
