Using a powder scintillator for a detection of gamma and X-rays allows to create detectors of various shapes, moreover the handling and fabrication of such scintillators is much easier than in the case of large or thin monocrystals. We report on the application of YAlO${}_3$:Ce powder to Mössbauer spectroscopy. The detection efficiency and the energy resolution of the scintillators made of powders of two different granularities (grain size $\le 30\mathrm{\mu }\mathrm{m}$ and 50–$70\mathrm{\mu }\mathrm{m}$) were investigated. The powder scintillators exhibited a comparable energy resolution and detection efficiency as YAlO${}_3$:Ce monocrystal with thickness of $400\mathrm{\mu }\mathrm{m}$. Burying the YAlO${}_3$:Ce grains into the epoxy resin increased the energy resolution of powder scintillators. The studied scintillators were found to be suitable for experiments in Mössbauer spectroscopy. The performance of YAP is also compared to the NaI:Tl scintillator.

使用粉末闪烁体来检测伽马射线和 X 射线允许创建各种形状的探测器，而且这种闪烁体的处理和制造比大或薄单晶的情况容易得多。我们报告YAlO的应用${}_3$:Ce 粉末到穆斯堡尔光谱。由两种不同粒度（粒度）粉末制成的闪烁体的检测效率和能量分辨率$\le 30\mathrm{\mu }\mathrm{米}$ 和 50–$70\mathrm{\mu }\mathrm{米}$) 进行了调查。粉末闪烁体表现出与 YAlO 相当的能量分辨率和检测效率${}_3$:Ce 单晶，厚度为 $400\mathrm{\mu }\mathrm{米}$. 埋葬 YAlO${}_3$:Ce 颗粒进入环氧树脂提高了粉末闪烁体的能量分辨率。发现所研究的闪烁体适用于穆斯堡尔光谱实验。YAP 的性能也与 NaI:Tl 闪烁体进行了比较。
