We report on measurements of differential cross sections (DCSs) for electron impact excitation of a series of Rydberg electronic-states in α-tetrahydrofurfuryl alcohol (THFA). The energy range of these experiments was 20-50 eV, while the scattered electron was detected in the 10°-90° angular range. There are currently no other experimental data or theoretical computations against which we can directly compare the present measured results. Nonetheless, we are able to compare our THFA DCSs with earlier cross section measurements for Rydberg-state electronic excitation for tetrahydrofuran, a similar cyclic ether, from Do et al. [J. Chem. Phys. 134, 144302 (2011)]. In addition, "rotationally averaged" elastic DCSs, calculated using our independent atom model with screened additivity rule correction approach are also reported. Those latter results give integral cross sections consistent with the optical theorem, and supercede those from the only previous study of Milosavljević et al. [Eur. Phys. J. D 40, 107 (2006)].
我们报告了关于α-四氢糠醇(THFA)中一系列里德堡电子态的电子碰撞激发的微分截面(DCS)测量结果。这些实验的能量范围是20 - 50电子伏特,同时在10° - 90°角范围内检测散射电子。目前没有其他实验数据或理论计算结果可让我们直接与当前测量结果进行比较。尽管如此,我们能够将我们的THFA DCS与Do等人[《化学物理杂志》134, 144302 (2011)]对类似环状醚四氢呋喃的里德堡态电子激发的早期截面测量结果进行比较。此外,还报告了使用我们的具有屏蔽加和规则校正方法的独立原子模型计算的“旋转平均”弹性DCS。后一组结果给出的积分截面与光学定理一致,并且取代了Milosavljević等人[《欧洲物理杂志D》40, 107 (2006)]之前唯一一项研究的结果。
