In medium-energy pion physics, considerable progress has been made in understanding the propagation and absorption of pions (deltas) in the nuclear medium. An experiment to study neutrino oscillations is being planned at LAMPF with substantial involvement from Argonne. A major effort is being devoted to the scientific and technical considerations involved in proposing to build a multi-GeV C.W. electron accelerator: GEM at Argonne. In heavy-ion physics, the superconducting linac booster is being used with increasing scientific profit. Construction of the ATLAS facility began in FY 1982 and all progress has been on schedule. The importance of the time component of the weak axial-vector current has been studied through the ..beta.. decay of /sup 16/N. A precision measurement is under way of the /sup 7/Be(p,..gamma..) cross section, one of the key components in the solar neutrino anomaly. In nuclear theory, the coupled-channel code for treating heavy-ion inelastic scattering was completed and application to particular experiments began. Nuclear structure theory was applied to interpret decays of high-spin states and inelastic pion scattering. Results of particular interest were obtained in the nuclear force program where the inclusion of 3-body forces led to simultaneous improvement in the binding of /sup 3/He and /sup 4/He and saturation of nuclear matter. The atomic physics research consists of six experimental programs as follows: (1) dissociation and other interactions of energetic molecular ions in solid and gaseous targets; (2) electron spectroscopy with fast atomic and molecular-ion beams; (3) beam-foil research and collision dynamics of heavy ions; (4) photoionization-photoelectron research; (5) high-resolution, laser-rf spectroscopy with atomic and molecular beams; and (6) theoretical atomic physics.
