A brief review of the technique of angle-resolved photoelectron spectr
oscopy as used in conjunction with synchrotron radiation is given. Exa
mples of the use of the technique which emphasise the collection of fu
ll-hemisphere data are presented, covering the determination of Fermi
surface topology and photoelectron diffraction/holography. An example
of an investigation of quantum size effects and of the use of magnetic
circular dichroism to explore the interaction of spin-orbit and excha
nge effects in iron is also provided.
