The highlight of the Argonne Physics Division during the past year (1985/86) has been the completion and dedication of the final superconducting linac stages of the ATLAS system and the beginning of the research program that utilizes the full capabilities of that system. The transition to using the full ATLAS and the new experimental area has been a smooth one and the research program is beginning to bear fruit. The experimental facilities have also come into operation with three major components, consisting of the first stage of a gamma detection system incorporating an array of Compton-suppressed germanium detectors and BGO total energy detectors, a magnetic spectrograph of the Enge split-pole design, with a focal-plane detector system adapted to heavy ions, and a new scattering facility with a number of features. Interesting new data are emerging on quasi-elastic processes, on the transition between fission and quasi-fission and the study of nuclear structure at high spin. The past year has also seen the merging of the nuclear research in the Argonne Chemistry Division, mostly in heavy-ion and medium-energy nuclear physics, with the Physics Division. The merger is leading to full cooperation within the larger group and will help broaden and strengthen the total effort in nuclear physics. In medium-energy physics the year has seen the successful execution of an experiment at the SLAC NPAS station to study the delta resonance in nuclei. Progress is being made in the effort at Fermilab on deep inelastic muon scattering, on the development of a tensor polarized gas deuterium target for use with storage rings, and on the LAMPF neutrino oscillation experiment. In theoretical nuclear physics an effort is continuing on investigating the relevant degrees of freedom in the microscopic dynamics of nuclei and the importance of three-body forces. 51 figs., 2 tabs.
