The proceedings of the August-September 1993 NATO Advanced Study Institute comprise lectures and contributions on topics in cluster radioactivity, fission and fusion, the production of very heavy elements, nuclear structure described with microscopic and collective models, weak interaction and double beta decay, nuclear astrophysics, and heavy ion reactions from low to ultrarelativistic energies. The volume begins with the opening lecture of the ASI by W. Greiner on the "Present and Future of Nuclear Physics," showing the most important new directions of research and the interdisciplinary relations of nuclear physics with other fields of physics.
