In this study, we represent the track response data of poly (allyl diglycol carbonate) (PADC) using the number of interactions with the stopping medium induced by secondary electrons. The N umber of I nteractions induced by S econdary E lectrons (NISE) is calculated using a Monte Carlo simulation code in Geant4-DNA. The description of the track response data given by NISE is improved compared with those proposed previously based on the stopping power and Radial Electron Fluence around Ion Tracks (REFIT). We also simulate the removal cross sections of the carbonate ester bond in PADC irradiated with protons and heavy ions (He, C, and Fe) based on the NISE. A radiation-oxidation kinetics model is combined with the estimation obtained in the present study. Discrepancies are found between the experimental results and our present simulation even after applying the radiation-oxidation kinetics model in the low stopping power region (<10 eV). Our results demonstrate that the interactions among electrons lying within the low-energy region (<7.4 eV) and the energy dependence of the yields due to bond breaks are crucial for obtaining more accurate estimation.

基于二次电子诱导的相互作用数改进聚（烯丙基二甘醇碳酸酯）中形成潜在轨迹的机制的标准

在这项研究中，我们使用二次电子诱导的与停止介质的相互作用次数来表示聚（烯丙基二甘醇碳酸酯）（PADC）的轨迹响应数据。使用 Geant4-DNA 中的 Monte Carlo 模拟代码计算二次电子 (NISE) 引起的相互作用数。NISE 给出的轨道响应数据的描述与先前基于停止本领和离子轨道周围的径向电子通量 (REFIT) 提出的那些相比得到了改进。我们还基于 NISE 模拟了质子和重离子（He、C 和 Fe）辐照的 PADC 中碳酸酯键的去除截面。辐射氧化动力学模型与本研究中获得的估计相结合。即使在低停止功率区域 (<10 eV) 中应用辐射氧化动力学模型后，实验结果与我们目前的模拟之间仍存在差异。我们的结果表明，位于低能量区域 (<7.4 eV) 内的电子之间的相互作用以及由于键断裂导致的产率的能量依赖性对于获得更准确的估计至关重要。
