Abstract

[GRs are collective phenomenon. They can be viewed as a coherent superposition of one-particle one-hole (1p-1h) interactions. The nucleon in the target nucleus can be excited into bound or quasi-bound states which gives rise to the 1p-1h state of the target nucleus. The excitation strength tends to be concentrated, by constructive superposition of 1p-1h excitations, into one or few of the levels in each shell. Thus, mathematically if the observed resonance exhausts a large fraction of the corresponding transition strength (sum rule) it is identified as a giant resonance. This chapter covers various theoretical concepts underlying the physics of GRs and describes the framework used for the analysis of the experimental data.]
