我们用高灵敏度和高分辨率（$e, 2e$）光谱仪给出了电子碰撞诱导氖价壳电离和激发的实验和理论结果。解决了以往电子动量谱结果的争议。55.83和71.50 eV的卫星主要归因于${\phantom{\rule{4pt}{0ex}} ^{2}P$流形，并混合了一些${}^{2}S$，而不是早期电子动量谱所分配的纯${}^{2}S$。55.83 eV下卫星的动量分布与Watanabe等人的报道一致[J]。电子Spectrosc。遗传代数。Phenom 142, 325(2005)]，但与Samardzic等人的结果不一致。《中华医学会杂志》第48卷，第4390卷（1993）。卫星55.83 eV的动量分布观测值与平面波冲量近似计算值的差异表明理论方法有待进一步改进。
We present experimental and theoretical results for electron-impact-induced ionization and excitation of the neon valence shell by using a highly sensitive and high-resolution ($e, 2e$) spectrometer. The controversies in previous electron momentum spectroscopic results have been resolved. The satellites at 55.83 and 71.50 eV are mainly attributed to a ${\phantom{\rule{4pt}{0ex}}}^{2}P$ manifold, and mixed up with some ${}^{2}S$, not a pure ${}^{2}S$ as were assigned by the earlier electron-momentum spectroscopy. Our experimental momentum distribution for the satellite at 55.83 eV is consistent with that reported by Watanabe et al. [J. Electron Spectrosc. Relat. Phenom 142, 325 (2005)], but not consistent with Samardzic et al.'s results [Phys. Rev. A 48, 4390 (1993)]. The difference between the observed momentum distribution of the satellite at 55.83 eV and the calculations with the plane-wave impulse approximation suggests the need for further improvement of the theoretical methods.
