我们目前的实验总截面的电子散射从糠醛的能量范围从10至1000 eV，使用双静电分析仪气体电池电子传输实验测量。这些结果进行了比较，糠醛的理论数据，以及实验和理论值的结构相似的分子呋喃和四氢呋喃。测量的总截面与用屏蔽修正加和规则的独立原子模型及干涉法计算的结果一致。在较高的电子能量的区域中，从500 eV到10 keV，总的电子散射截面也使用基于分子目标的电子数和偶极极化率的半经验模型来估计。再加上最近测得的微分和积分截面，和糠醛的能量损失谱，目前的总截面数据几乎完成的数据集，所需的数值模拟的低能量电子过程中糠醛，覆盖范围内的弹丸能量从几个电子伏高达10千电子伏。
We present experimental total cross sections for electron scattering from furfural in the energy range from 10 to 1000 eV, as measured using a double electrostatic analyzer gas cell electron transmission experiment. These results are compared to theoretical data for furfural, as well as to experimental and theoretical values for the structurally similar molecules furan and tetrahydrofuran. The measured total cross section is in agreement with the theoretical results obtained by means of the independent-atom model with screening corrected additivity rule including interference method. In the region of higher electron energies, from 500 eV to 10 keV, the total electron scattering cross section is also estimated using a semi-empirical model based on the number of electrons and dipole polarizabilities of the molecular targets. Together with the recently measured differential and integral cross sections, and the furfural energy-loss spectra, the present total cross section data nearly complete the data set that is required for numerical simulation of low-energy electron processes in furfural, covering the range of projectile energies from a few electron volts up to 10 keV.
