In this work we compare characteristics of Auger neutralization of [Formula: see text] ions at noble metal and free-electron metal surfaces. For noble metals, we find that the position of the energy level of He with respect to the Fermi level has a non-negligible influence on the values of the calculated Auger rates through the evaluation of the surface dielectric susceptibility. We conclude that even though our calculated rates are accurate, further theoretical effort is needed to obtain realistic values of the energy level of He in front of these surfaces.

原子能级变化对贵金属表面俄歇中和率的影响。


在这项工作中，我们比较了贵金属和自由电子金属表面[分子式：见文本]离子的俄歇中和特性。对于贵金属，通过表面介电敏感性的评估，我们发现He能级相对于费米能级的位置对计算俄歇速率的值具有不可忽略的影响。我们的结论是，尽管我们计算的速率是准确的，但仍需要进一步的理论努力才能获得这些表面前面的 He 能级的实际值。
