Abstract

The high-resolution photoemission spectroscopy of conventional superconductors is reviewed. It is shown that with the presently available resolution (0.360 meV using laser excitation) the gap structure (like two gaps in MgB2 or an anisotropic gap in CeRu2) can be resolved with a high degree of accuracy. It is pointed out that the use of low-photon-energy laser excitation (10 eV or less) is an alternative way (as compared to the use of high photon energies) to make more bulk-sensitive measurements with photoemission spectroscopy.
