Brian Bransden retired at the end of September 1991, and a meeting was held on 26-27 September at the University of Durham to mark the occasion. Brian has worked on a wide range of problems in theoretical physics, mainly involving scattering phenomena. For many years, he has been engaged primarily in studies of atomic physics, and he has made important contributions to the theory of charge exchange collisions and of electron and positron scattering. At the Durham meeting, international experts reviewed the state of the art in each of these subject areas.
