摘　　要：基于自行设计的实验平台,利用碘化钠和溴化镧闪烁探测器对60Ni级联γ跃迁中两条γ射线(1173.3keV和1332.5keV)的角关联关系进行了测量.基于具体的实验条件对理论值进行修正,得到的实验数据能和其符合得很好,即得到的理论跃迁方式能和60Ni实际的跃迁方式和跃迁性质相吻合.说明该实验设备及方法是可行的,可以用于级联γ辐射角关联关系的测量,有助于学生对原子核γ跃迁有更深入的认识.Based on the experiment platform we designed, the angular correlation between the γ rays （1173. 3keV and 1332.5keV） from 60Ni cascade transition is measured by the NaI and LaBr3 detectors. According to the actual experiment situation, the theoretical value is modified. It is shown that the modified value and the experimental value are in agreement well, namely, the transition form we confirmed from experiment is just the actual one. It is proved that our equipment and method are effective and can be applied to analogous experiments on γ cascade transition. This experiment is helpful to get students further understanding on γ transition.
