Atomic Physics Research with Synchrotron Radiationmajor advances in facilities for the production of synchrotron light that are certain to engender a great increase in its use for the exploration of atomic inner shells. This appears to be a good time, therefore, for some retrospection and a survey, albeit brief and incomplete, of applications of synchrotron light in atomic and molecular physics.

The Stability of Fuzzy Control Systems,ons from the target atom may be ejected or excited to different orbits. In many of these atomic processes, the quantitative study of the transition based on the straightforward independent-particle calculation, when compared with the experimental measurement, fails to provide a satisfactory physical

On the experimental side this became possible due to the development of high-resolution .-ray spectrometers which, besides for .-ray spectroscopy, were also used for the stud

Firstly any structure which emerges from the Dirac one-electron problem shares with it questions about proper accounting of the role of negative-energy

Fuzzy Modeling and Fuzzy Control detected final state. This information is usually formulated in terms of transition probabilities. In order to obtain well-defined transition probabilities experimentally, one tries to define initial and final states as well as possible by the experimental setup. In an ideal case, initial and final

Fuzzy Modeling and Fuzzy Control scattering. Except in the forward direction, this scattering (for any given angle) is increasingly dominated by scattering from the inner atomic shells as one proceeds from X-ray toward γ-ray photon energies. Depending therefore on the choice of energy and scattering angle, the process can be used
