Book excerpt: Angle Resolved Photoemission Spectroscopy (ARPES) is the major experimental method used to investigate the electronic structure of solids. It directly probes the electron-wave-vector dependence of occupied electronic states. The photoemission spectrum is modelled by a spectral function A(k,E) with electron wave vector k and binding energy E which includes electron-electron interactions by a complex self-energy. Bandstructures of metals are often successfully calculated by density-functional theory without self-energy corrections. For certain solids such as the noble metal Cu, the one-electron band-structure picture of density-functional theory agrees very well with the E (k) dispersion obtained ARPES. However for its neighbour in the periodic system, the 3d transition metal Ni, strong effects of electron correlation on core-level and valence-band spectra have been established.
