It is proposed to continue a comprehensive experimental                 study of the excitation of inner electron shells of heavy atoms                 by 0.1 to 3.0 MeV ion-atom collisions.  This investigation will                 shed light on curve crossing and other quasimolecular phenomena                 which occur at small internuclear separations.  Two scattering                  apparatuses are available for this study:  The first, completed                 during the present NSF grant period, detects Auger electrons or                 characteristic x rays in coincidence with ions scattered to                     angles between 2 and 20 degrees by single collisions with gaseous               targets.  The nature of the Auger electron-ion coincidence                      spectra obtained with this apparatus is surprising and the                      primary thrust of this proposal will be to continue with this new               effort.  The data obtained is differential in nature and provides               unique and detailed information about the excitation and decay of               unusual atomic and molecular states.  The second apparatus is a                 high resolution x-ray spectrometer and will be used to                          investigate the radiative decays corresponding to the above Auger               decays.  These efforts will be supplemented with calculations                   using a Dirac-Fock program.  It is the total of these three                     efforts that will provide new and unique information on the                     interaction of ion beams with matter.                                                   The results of this research will aid in the understanding              of basic processes in atomic interactions, and will be of use in                such practical problems as controlling high-temperature plasmas                 and modelling naturally-occurring phenomena.
