摘要

The significant modifications to our recently constructed electron momentum spectrometer have been implemented.Compared with our previous report,the energy and the angle resolutions are significantly improved and reach △E=0.45 eV,△θ=±0.53°and △φ=±0.84°,respectively.Moreover,the details of data reduction and the relation between azimuthal angle range and the sensitivity are discussed.
