The extended track interaction model (ETIM) has been formulated to explain the TL-fluence response for peak 5 to heavy ions using radial dose distributions produced by the ions in LiF and their luminescent centre occupation probability distributions. In this work, an experimental study of the TLD-100 fluence response to carbon and oxygen ions and its interpretation in terms of a Monte Carlo simulation of ETIM applied to peak 5 are presented. Irradiations were performed with 7.34 and 10.3 MeV 12C and 8.34 MeV 16O ions in the fluence interval between 2 x 10(7) and 2 x 10(11) cm(-2). Individual glow curve responses show the expected increase of supralinearity as the peak temperature increases. Data for peak 5 show a weak dependence with energy. These latter results are difficult to understand when one considers the differences in the expected radial occupancies for different ion energies.
扩展径迹相互作用模型（ETIM）已被构建，用于利用锂氟化物中离子产生的径向剂量分布及其发光中心占据概率分布来解释重离子峰5的热释光通量响应。在这项工作中，展示了对TLD - 100对碳离子和氧离子的通量响应的实验研究，以及根据应用于峰5的ETIM蒙特卡罗模拟对其进行的解释。使用能量为7.34和10.3 MeV的12C离子以及8.34 MeV的16O离子在通量区间2×10(7)至2×10(11) cm(-2)内进行辐照。单个发光曲线响应表明，随着峰值温度升高，超线性预期增加。峰5的数据显示出对能量的弱依赖性。当考虑不同离子能量下预期径向占有率的差异时，后一结果难以理解。
