We report a joint theoretical and experimental investigation on low-energy electron scattering by dimethyl and diethyl ethers. The experimental elastic differential cross sections were measured at impact energies from 1 eV up to 30 eV and scattering angle range of 10° to 130°. Theoretical elastic differential, integral and momentum-transfer cross sections are calculated at impact energies up to 30 eV, employing the Schwinger multichannel method implemented with norm-conserving pseudopotentials, in the static-exchange and static-exchange plus polarization approximations. Our experimental and theoretical results for dimethyl and diethyl ether are compared with previous data for their isomers, ethanol and butanol, respectively. These comparisons reveal that although the cross sections for the ether and its respective alcohol present similar magnitudes, the angular behavior of their differential cross sections shows some significant differences. From the analysis of the integral cro...

二甲醚和二乙醚散射低能电子的理论和实验研究

我们报告了关于低能量电子通过二甲基和二乙醚进行的联合理论和实验研究。在1eV至30eV的冲击能量和10°至130°的散射角范围内测量了实验的弹性微分截面。理论上的弹性微分，积分和动量传递横截面是在静力交换和静交换加极化近似的情况下，采用具有规范守恒伪势的Schwinger多通道方法计算的，其冲击能量最高为30 eV。我们将二甲基和二乙醚的实验和理论结果分别与以前的异构体乙醇和丁醇的数据进行了比较。这些比较表明，尽管醚和其各自的醇的横截面呈现相似的幅度，但它们的微分横截面的角行为显示出一些显着差异。从积分cro的分析来看...
