The investigation of excitation and decay processes, such                  as electron and x-ray emission, which takes place when heavy                    ions collide with heavy ions at low MeV energies, will be                       continued.  A previously unidentified mechanism is responsible                  for the prompt emission of 20-25 electrons in Kr-Kr and Kr-Xe                   Systems, ejected in about 10(-17) seconds, with a continuous                    energy distribution of the emitted electrons.  It is planned to                 study this effect to determine its origin and generality,                       utilizing two techniques involving single collisions of                         projectiles scattered through large (one to twenty degree)                      angles.  One experiment will determine ejected electron                         energies in coincidence with the scattered ion.  The second                     experiment will measure both the scattered ion and the recoil                   ion charge states in coincidence, to determine how ionization                   is shared between the two ions.  Results will be compared with                  data for lighter collision systems as well as ion-solid                         systems, to determined whether apparent common features in the                  electron emission spectra do have a common origin.
