在潘宁电离电子能谱中，分析目标 T（气体或固体）与亚稳态稀有气体原子 A* 碰撞时发射的电子的动能。这种电子能谱对固体的最外层表面有选择性地敏感，因为亚稳态原子不会渗透到内层。此外，它还提供了暴露在最外表面层之外的各个轨道的局部电子分布信息。讨论了潘宁光谱的这些独特特征在有机固体（包括 Langmuir-Blodgett 薄膜）表面表征中的应用。简要描述了潘宁光谱技术和气相分子的潘宁电离过程。
In Penning ionization electron spectroscopy, the kinetic energy of electrons ejected by collisions between targets T (gas or solid) and metastable rare gas atoms A* is analyzed. This electron spectroscopy is selectively sensitive to the outermost surface layer of solids, since metastable atoms do not penetrate into inner layers. Furthermore, it provides information on the local electron distribution of individual orbitals exposed outside the outermost surface layer. The application of these unique features of Penning spectroscopy to the surface characterization of organic solids, including Langmuir-Blodgett films, is discussed. Both a Penning spectroscopy technique and the process of Penning ionization of gas-phase molecules are briefly described.
