Cerium doped Lanthanum halide scintillators are useful in γ-ray spectroscopy due to their excellent energy resolution and high stopping power. The response of Compton electrons in 1″ × 1″ cylindrical LaCl₃:Ce scintillator was recorded using a PIXIE-4 digital data acquisition system having no requirement of any external pulse-processing unit and coincidence unit, which makes the whole measurement setup very compact. The intrinsic energy resolution of Compton electrons in LaCl₃:Ce was measured employing the Wide Angle Compton Coincidence Technique (WACCT) for energies ranging from 100 keV to 1 MeV by using ¹³⁷Cs, ⁶⁰Co and ²²Na γ-ray sources. The effect of coincidence energy gating window was also studied. A good agreement between the present results obtained using a digital method and the results reported in the literature with the analogue method has been observed.

铈掺杂的卤化镧闪烁体由于其出色的能量分辨率和高停止能力而可用于 γ 射线光谱。康普顿电子在 1″ × 1″ 圆柱形 LaCl ₃ :Ce 闪烁体中的响应是使用 PIXIE-4 数字数据采集系统记录的，不需要任何外部脉冲处理单元和符合单元，这使得整个测量装置非常紧凑. 康普顿电子在 LaCl ₃ :Ce 中的固有能量分辨率是通过使用¹³⁷ Cs、⁶⁰ Co 和²²使用广角康普顿符合技术 (WACCT) 测量的，能量范围从 100 keV 到 1 MeVNa γ 射线源。还研究了重合能量门控窗口的影响。已经观察到使用数字方法获得的当前结果与文献中使用模拟方法报告的结果之间的良好一致性。
