Giant Resonances: Fundamental High-Frequency Modes of Nuclear ExcitationGiant 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 behavior 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
