    We have developed a new apparatus to measure the energy spectra of field emission electrons with the high resolution. By using the apparatus, we have measured the high-resolution spectra of the electrons emitted from the Nb(100) tip at liquid-nitrogen temperature and detected the electronic surface (sub-surface) resonance states and the atomic vibrations of chemisorbed hydrogen.
