International Symposium on Nuclear Structure Physics : celebrating the career of Peter von Brentano : University of Göttingen, Germany, 5-8 March 2001

Nuclear structure physics is undergoing a major revival, full of activities and excitement. On the experimental side, this is being made possible by advances in detector technology and accelerator capabilities that give access to data and nuclei (especially exotic nuclei far from stability) never before accessible. On the theoretical side, new concepts, ideas and computational techniques are advancing our understanding of effective interactions, nucleonic correlations, and symmetries of structure. This volume covers a broad range of topics on nuclear structure, including: collective excitations; proton-neutron excitation modes; phase transitions; signatures of structure; isospin; structure at both high- and low-angular momenta; recent developments in nuclear theory; the vast new realm of exotic nuclei far from the valley of stability; and the latest technological advances of detectors and facilities which will lead this branch of physics into the future.
