High-energy giant resonances
A semimicroscopic approach to the description of high-energy giant resonances is briefly discussed. The approach is based on the continuum version of the random phase approximation and the phenomenological treatment of the spreading effect. The realistic nuclear mean field and the Landau-Migdal interaction in the particle-hole channel are used in the calculations with the main symmetries of the model Hamiltonian taken into account. Most of the available experimental data on properties of high-energy giant resonances (including decay characteristics) are satisfactorily described within the semimicroscopic approach. Properties of high-energy giant resonances not yet observed experimentally are predicted.
