The Physics Division's program in nuclear physics covers a broad span of activities within that discipline. The object of this research is to understand the properties of atomic nuclei, their structure, the mechanisms of nuclear reactions, and manifestations of fundamental symmetries in nuclei. Work is carried out under a variety of subprograms: theory, heavy-ion physics, medium-energy physics and nuclear research. These categories do not represent a sharp separation between people--individual scientists often work in several different areas. This flexibility allows scientific problems to be addressed with a variety of techniques, and it avoids limiting individual scientists' activities to a particular subdiscipline.
