论文摘要
已经使用速度切片成像（VSI）技术研究了低能电子附着在二硫化碳上的完全解离动力学。已经获得了S-和CS片段离子的离子屈服作为在5至11 eV范围内入射电子能的功能。在该能量范围内，在6.2 eV和7.7 eV处的S离子有两个共振，在6.2 eV下仅获得了一个共振。已经测量了这些片段负离子在这些共振周围不同入射电子能在不同入射电子能的角度分布。从这些片段阴离子的角度分布中，我们发现临时负离子的弯曲导致角度分布与预期的分布发生显着变化。
Complete dissociation dynamics of low-energy electron attachment to carbon disulfide have been studied using the velocity slice imaging (VSI) technique. The ion yields of S- and CS- fragment ions as the function of incident electron energy in the range 5 to 11 eV have been obtained. Two resonances for S- ions at around 6.2 eV and 7.7 eV and only one resonance for CS- ions at around 6.2 eV have been obtained in this energy range. The kinetic energy and the angular distributions of these fragment negative ions at different incident electron energies around these resonances have been measured. From the angular distribution of these fragment anions, we have found that the bending of the temporary negative ions causes a significant change in the angular distribution from the expected one.
