摘要：氧分子O2在中等速度范围（p+-能量：17-800 keV，e--能量：0.2-2 keV）与质子和电子碰撞时解离。在真空紫外、可见光和近紫外光谱范围内检测到激发原子和单电离片段以及单电离分子的荧光。提供 VUV（46-131 nm）和近紫外/可见光（340-605 nm）光谱范围的高分辨率光谱。已经确定了在 VUV 中产生荧光的解离电离和激发的绝对发射截面。结果与已发表的数据进行比较。
Abstract:Molecular oxygen O2 was dissociated in collisions with protons and electrons in the intermediate velocity range (p+-energies: 17-800 keV, e--energies: 0.2-2 keV). Fluorescence from excited atomic and singly ionised fragments and from singly ionised molecules was detected in the VUV and in the visible and near UV spectral range. Highly resolved spectra are presented for the VUV (46-131 nm) and the near UV/visible (340-605 nm) spectral range. Absolute emission cross-sections have been determined for dissociative ionisation and excitation leading to fluorescence in the VUV. Results are compared with published data.
