The activities of the nuclear chemistry program at Indiana University during the period September 1, 1982 to August 31, 1983 are reviewed. As in the past, these investigations have focused on understanding the properties of nucleus-nucleus collisions at low-to-intermediate energies. During the past year new programs have been initiated at the National Superconducting Cyclotron Laboratory at Michigan State University and the Hollifield Heavy-Ion Research Facility at Oak Ridge. With the unique beams provided by these accelerators we have extended our previous studies of energy dissipation phenomena into new energy regimes. The MSU measurements, performed with E/A = 15 to 30 MeV /sup 14/N beams, combined with recent results we have obtained at IUCF, have indicated the existence of a saturation in the average amount of linear momentum that can be transferred in nucleus-nucleus collisions. This saturation value is about 140 (MeV/C)/A and occurs at beam energies in the E/A approx. 30 to 50 MeV range for /sup 3/He- to /sup 20/Ne-projectiles. At HHIRF, studies of the /sup 56/Fe + /sup 56/Fe reaction at E/A = 14.6 MeV have provided additional evidence for structure in the energy spectra of projectile-like fragments formed in symmetric collisions. Studies of near-barrier /sup 56/Fe-induced reactions have continued at the Lawrence Berkeley Laboratory SuperHILAC.
