Publication Date: Research Org.: Lawrence Berkeley National Lab. beta.-delayed proton emitters in the rare earth region are being investigated at the SuperHILAC. beta.-delayed proton more » decay of odd-odd T/sub z/ = -2 nuclides. Research in the area of exotic nuclei has led to the observation at the 88-Inch Cyclotron of the. Nuclear structure investigations at these accelerators continue to be directed toward the understanding of the behavior of nuclei at high angular momentum. Recent experiments have contributed to our understanding of the nature of light-particle emission in deep-inelastic collisions, of peripheral reactions, incomplete fusion, fission, and evaporation. Reaction mechanism work dominates the heavy-ion research at the 88-Inch Cyclotron and the SuperHILAC. These relativistic experiments have shed important light on the degree of equilibration for central collisions, the time evolution of a nuclear collision, the nuclear density and compressional energy of these collisions, and strange particle production. Results from Bevalac experiments employing a wide variety of heavy ion beams, along with new or upgraded detector facilities (HISS, the Plastic Ball, and the streamer chamber) are contained in this report. Complementary programs in light-ion nuclear science, in nuclear data evaluation, and in the development of advanced instrumentation are also carried out. Heavy-ion investigations continue to dominate the experimental and theoretical research efforts. ![]() This report summarizes the scientific research carried out within the Nuclear Science Division between July 1, 1981, and September 30, 1982.
