Abstract
Much of present understanding of atomic and molecular structure and dynamicswas gained through studies of photon--atom interactions. In particular,observations of the emission, absorption, and scattering of X rays havecomplemented particle-collision experiments in elucidating the physics ofatomic inner shells. Grounded on Max von Laue's theoretical insight andthe invention of the Bragg spectrometer, the field's potential underwent astep function with the development of synchrotron-radiation sources. Notablycurrent third-generation sources have opened new horizons in atomicand molecular physics by producing radiation of wide tunability andexceedingly high intensity and polarization, narrow energy bandwidth, andsharp time structure. In this review, recent advances insynchrotron-radiation studies in atomic and molecular science are outlined.Some tempting opportunities are surveyed that arise for future studiesof atomic processes, including many-body effects, aspects offundamental photon--atominteractions, and relativistic and quantum-electrodynamic phenomena.PACS Nos.: 32.20J, 32.20R, and 07.65E
