本文的目的是估计MgO的光谱反射率作为层厚度的函数在LaBr3：5%Ce晶体周围。计算了闪烁体的参考发射光谱，平均来自文献的15个实验趋势。MgO反射率的调查提供了实验数据的波长范围内的利益没有厚度的信息，而与尺寸的事实的趋势，发现在相邻的波长区域。开发了一种算法，用于在给定厚度的感兴趣波长区域内对光谱数据进行插值。附录A中总结了LaBr3：Ce反射器之间的比较。结果以加权平均值以及数值趋势的形式呈现，特别是作为封装晶体的Monte Carlo模拟的输入。
Present paper is aimed to estimate the spectral reflectance of MgO as a function of layer thickness around LaBr3:5%Ce crystals. A reference emission spectrum of scintillator was calculated averaging 15 experimental trends from literature. A survey on MgO reflectance provided experimental data in the wavelength region of interest without thickness information, while trends with dimensional facts were found in the adjacent wavelength region. An algorithm was developed for interpolating spectral data in the wavelength region of interest for given thickness. A comparison between reflectors for LaBr3:Ce is summarized in Appendix A. Results are presented in form of weighted average values as well as numerical trends suitable, in particular, as input for Monte Carlo simulations of encapsulated crystals.
