    "abstract": "A new class of giant resonances in nuclei is discussed, i.e., giant\nresonances built on other giant resonances. These resonances are observed with\nvery large cross sections in relativistic heavy ion collisions. A great\nexperimental and theoretical effort is underway to understand the reaction\nmechanism which leads to the excitation of these states in nuclei, as well as\nthe better microscopic understanding of their properties, e.g., strength,\nenergy centroids, widths, and anharmonicities.",
