This investigation focuses on whether the experimentally observed changes, in supralinearity f(D) as a function of recombination temperature, can be, successfully, predicted by the Unified Interaction Model (UNIM). To resolve this question, the measurement of f(D) has been carried out for glow peaks 4, 5 and 5b in LiF:Mg,Ti (TLD-100) at two different heating rates and UNIM analysis is used in an attempt to arrive at a consistent/physically reasonable explanation of all the f(D)/heating rate data for the three glow peaks. It is demonstrated that in addition to the variation in the luminescence and competitive centre capture cross section with temperature changes in the ks (the geminate recombination coefficient) parameter as a function of temperature is also required in order to predict the changes in f(D).
本研究聚焦于实验观测到的超线性f(D)随复合温度的变化，能否被统一相互作用模型（UNIM）成功预测。为解决这个问题，在两种不同加热速率下对LiF:Mg,Ti（TLD - 100）中的辉光峰4、5和5b进行了f(D)测量，并使用UNIM分析来尝试对三个辉光峰的所有f(D)/加热速率数据给出一致的/物理上合理的解释。结果表明，为了预测f(D)的变化，除了发光和竞争中心俘获截面随温度变化外，还需要ks（双分子复合系数）参数随温度的变化。
