         Synchrotron Radiation Experiments in Atomic Physics

Synchrotron emission provides a continuously tunable source of radiation
spanning the spectral range from the infra-red to the hard x-ray.  In the
vacuum ultraviolet and soft x-ray regimes, the photon energies are
sufficient to excite inner-shell electrons to localized states that overlap
with continuum states produced by ionization of outer shell electrons.
Detailed studies of the dynamics of the motion of the electrons in these
overlapping states provides a window onto the many-body effects caused by
the electron-electron interaction.   The talk will discuss the
manifestation of these effects with a particular focus on electron dynamics
in complex, open-shell atoms.   Both experimental and theoretical results
will be presented.
