电子表面共振是真空能级以上能量的准静止表面态。它们可以在LEED和其他电子散射实验中观察到窄强度波动。本文综述了低能表面共振带结构E (k∥（E =共振能，k∥=简化表面平行动量）的测量和解释的最新进展。强调了分析共振线形状对精确确定共振电平的重要性，并以W（001）表面的高分辨率LEED数据为例进行了分析。
Electronic surface resonances are quasistationary surface states at energies above the vacuum level. They may be observed as narrow intensity fluctuations in LEED and other electron scattering experiments. A survey of recent developments in the measurement and interpretation of low‐energy surface resonance band structure E (k∥ (E = resonance energy, k∥ = reduced surface‐parallel momentum) is presented. The importance of analyzing resonance lineshapes for accurate determination of resonance levels is emphasized, and high‐resolution LEED data for W(001) surface is analyzed as an example.
