Refracting instrument for ultraviolet inverse photoemission spectroscopy.
01 January 1988
An instrument is described for k-resolved ultraviolet inverse photoemission spectroscopy using a LiF lens monochromator and a rotatable high-perveance electron gun. The energy resolution from all sources at homega = 11 eV is 0.6 eV (FWHM). The angular spread of the incident electrons is calibrated using the properties of a well known and well characterized surface state on Cu (111), and is found to be 7degrees (FWHM).
