The main aim of this book is to provide a broad overview of nuclear physics in terms of both hadron-meson dynamics and quark-lepton dynamics. It covers topics such as elastic and inelastic scattering, spin-isospin responses and charge exchange reactions, giant resonances, nuclear clusters,nuclear physics with strange flavour, and others. All subjects are presented from the experimental point of view, and enough prerequisite material is included for the book to be accessible to graduate students. From this the reader is led through to discussions of the important questions of currentresearch. H. Ejiri is Director of the Research Centre for Nuclear Physics (RCNP) at the University of Osaka, Japan. H. Toki is Professor of Physics at the University of Osaka, Japan.
