WebThe energy resolution was set to be 0.2 eV. An inverse-photoemission spectrometer [6] with a low-energy electron gun of Erdman-Zipf type and a bandpass photon detector centered at 9.43 eV [7] was connected with photoemission spectrometer. The inverse-photomeission spectra were measured under 2.0×10 −10 Torr with the energy resolution of 0.56 eV.
