Giant Resonances : Fundamental High-Frequency Modes of Nuclear Excitation

Resonances are a common feature of many systems in nature. This book provides a comprehensive account of a similar phenomenon in atomic nuclei, the giant resonances. It describes experimental facts, how these are obtained, and how they fit into theoretical models. It also includes a short history and an overview of the main achievements.

Giant resonances are collective excitations of the atomic nucleus, a typical quantum many-body system. The study of these fundamental modes has in many respects contributed to our understanding of the bulk behaviour of the nucleus and of the dynamics of non-equilibrium excitations. Although the phenomenon of giant resonances has been known for more than 50 years, a large amount of information has been obtained in the last 10 years. This book gives an up-to-date, comprehensive account of our present knowledge of giant resonances. It presents the experimental facts and the techniques used to obtain that information, describes how these facts fit into theoretical concepts and how this allows to determine various nuclear properties which are otherwise difficult to obtain. Included as an introduction is an overview of the main facts, a short history of how the field has developed in the course of time, and a discussion of future perspectives.
