作为联邦大学圣卡洛斯卡洛斯（UFSCar）和加州州立大学（CSUF）之间建立的合作项目的一部分，我们报告了一个联合的理论-实验研究氯苯的弹性电子散射在低，中能量范围。更具体地说，实验弹性微分截面（DCS），在入射电子能量范围为1.0至800 eV和散射角范围为10°至130°，使用交叉束相对流技术测量。积分和动量传递截面由实验DCS的数值积分确定。从理论上讲，弹性微分，积分和动量转移截面计算使用的分子复合物的光学势模型与Padé近似技术的冲击能量范围从1.0到150 eV的组合。DCS的进一步计算在20至500 eV的能量范围内使用独立原子模型进行。我们的研究结果，这显着扩展了可用的电子散射截面为这个目标，在文献中现有的理论和实验数据进行比较。
We report a joint theoretical–experimental investigation on elastic electron scattering by chlorobenzene in the low- and intermediate-energy ranges as a part of a collaborative project established between the Federal University of São Carlos (UFSCar) and the California State University (CSUF). More specifically, experimental elastic differential cross sections (DCS), in the incident electron energy range of 1.0 to 800 eV and scattering angle range of 10° to 130°, were measured using the crossed-beam relative-flow technique. Integral and momentum-transfer cross sections were determined from the numerical integration over the experimental DCS. Theoretically, elastic differential, integral, and momentum-transfer cross sections were calculated using a combination of a molecular complex optical potential model with the Padé approximant technique for impact energies ranging from 1.0 to 150 eV. Further calculations of DCS were performed at an energy range of 20 to 500 eV using the independent-atom model. Our results, which significantly extend available electron scattering cross sections for this target, are compared to existing theoretical and experimental data in the literature.
