介绍了放射性核束弹性散射实验中测量的角分布进行归一化的方法。由于有限的测量角区及放射性核束有较大的发散度 ,采用了逐个事件计算的方法 ,在探测器空间分布区域用事先产生的一系列点构成的数据库模拟探测器边界 ,对这些点进行坐标转换 ,再进行选择判断 ,得到每个事件的几何探测效率。通过每个事件的几何探测效率推算到整个空间 ,得到实际的角分布。
The method of normalizing the angular distribution measured in the EHB scattering experiment is introduced. Due to the limited divergence of the measured angular region and the radionuclide beam, a method of event-by-event calculation was used to simulate the detector boundary using a database of a series of previously generated points in the spatial distribution of the detector, Coordinate conversion, and then choose to judge, to get the geometric detection efficiency of each event. Through the geometric detection efficiency of each event, the whole space is deduced to get the actual angular distribution.
