Particle-hole excitations are studied in terms of a single-particle representation consisting of bound states and resonant solutions (Gamow resonances) of a realistic Woods-Saxon potential. Within this representation a particle-hole resonant random phase approximation is developed. Using the resonant random phase approximation the escape widths of the multipole giant resonances in Pb208 are calculated and reasonable agreement with available experimental data is obtained.
