介绍了一个解释液体氙闪烁产额的综合模型。我们统一了各种定义的功函数丰富的文献中，并纳入所有可用的数据电子反冲闪烁产额。这导致更好地理解电子反冲，并有利于改进核反冲的描述。入射伽马能量范围为0（1千电子伏）至0（1兆电子伏）和0和O（10千伏/厘米）之间的电场被纳入这个启发式模型。我们展示了Geant 4实现的结果，但由于该模型有一些自由参数，因此在任何仿真包中的实现都应该很简单。我们使用一个准经验的方法，提高检测器校准和性能验证的目标。该模型将有助于未来探测器的设计和优化。这种模式也很容易推广到其他贵族元素。在本文中，我们奠定了详尽的模拟代码，我们称之为NEST（贵元素模拟技术）的基础。
A comprehensive model for explaining scintillation yield in liquid xenon is introduced. We unify various definitions of work function which abound in the literature and incorporate all available data on electron recoil scintillation yield. This results in a better understanding of electron recoil, and facilitates an improved description of nuclear recoil. An incident gamma energy range of O(1 keV) to O(1 MeV) and electric fields between 0 and O(10 kV/cm) are incorporated into this heuristic model. We show results from a Geant4 implementation, but because the model has a few free parameters, implementation in any simulation package should be simple. We use a quasi-empirical approach with an objective of improving detector calibrations and performance verification. The model will aid in the design and optimization of future detectors. This model is also easy to extend to other noble elements. In this paper we lay the foundation for an exhaustive simulation code which we call NEST (Noble Element Simulation Technique).
