一种新的角分布测量方法

A new method to measure γ ray angular distribution

介绍了一种用靶子的剩余放射性对各探测器进行相对探测效率归一，把六套ＢＧＯ（ＡＣ）ＨＰＧｅ探测器置于与束流方向成不同角度的位置上同时进行单谱测量，以完成γ射线角分布测量的新方法。

Presented is a new method to determine γ ray angular distribution with six BGO(AC)HPGe detectors, which are located at different angles relative to the beam direction, to measure γ rays simultaneously. The relative detection efficiencies for these detectors are normalized by using target radioactivity.
