利用光电子-俄歇电子重合技术的选择性，分离了OCS中L(2,3)MM俄歇谱中的S L(3)MM。通过这种方法，实现了最终OCS（2+）态的能量、宽度和相对强度与理论计算的直接比较。此外，在两种不同的光子能量下，测量了一些选定的俄歇电子与光电子的角分布。与非符合测量结果相比，符合角分布表现出明显的不对称性，并且依赖于光子能量和OCS（2+）最终态。
The selectivity of the photoelectron-Auger electron coincidence technique has been used to isolate the S L(3)MM contribution to the L(2,3)MM Auger spectrum in OCS. In this way, a direct comparison of the energies, widths, and relative intensities of the final OCS(2+) states with theoretical calculations has been achieved. Moreover, the angular distributions of some selected Auger electrons have been measured in coincidence with the photoelectron at two different photon energies. In contrast with the results of noncoincidence measurements, the coincidence angular distributions show a significant asymmetry and a dependence on the photon energy and OCS(2+) final state.
