Abstract
From the general theory of resonance nuclear reactions we derive the approach for the description of giant resonances as emerging out of the interplay of two types of collectivity: internal coupling by the residual interaction and external coupling via common decay channels. Implications for the observable giant resonance pattern are discussed. In particular, the structure at the unperturbed 1p-1h energy is predicted with the presumable enhancement for resonances built on the excited states. It is shown how the fragmentation over complicated configurations and the spreading width could be incorporated into the theory.
