利用同步辐射阈值光电子源，在20 eV ~ 16 meV的能量范围内，获得了电子与O2散射的绝对总截面，电子能宽仅为7 meV.在本研究中得到的总截面一般同意与以前的实验工作中得到的能量区域，以前的实验总截面彼此一致。在较低的能量，发现了几个特征，包括非常大的贡献，
An absolute total cross-section for electron scattering from O 2 is obtained in the energy range from 20 eV down to 16 meV with a very narrow electron energy width of 7 meV, using the threshold-photoelectron source employing synchrotron radiation. The total cross-section obtained in the present study generally agrees well with those obtained in previous experimental works in the energy region where the previous experimental total cross-sections agree with each other. At lower energies, several features are found, including the very large contribution of the
