具有半球形能量选择器的电子能量损失谱仪在低能量容量、分辨率、低能量响应函数校正、灵敏度和角度范围扩展至180°方面都得到了改进。扩展的容量允许更详细地观察卤化物中的阈值峰值和近阈值结构，观察CO2、N2O和CS2中的近阈值结构，以及观察CO2中2πu形状共振激发费米耦合振动的选择性。
The performance of an electron energy loss spectrometer with hemispherical energy selectors has been improved in terms of low energy capacity, resolution, response function correction at low energies, sensitivity, and extension of the angular range to 180°. The extended capacity permitted a more detailed observation of threshold peaks and near threshold structures in halogen halides, observation of near threshold structures in CO2, N2O and CS2 and the observation of selectivity in the excitation of Fermi-coupled vibrations by the 2Πu shape resonance in CO2.
