For the particle–hole dispersive optical model developed recently, a method is proposed for restoring unitarity weakly violated by a phenomenological description of the spreading effect. The method is implemented by performing a quantitative analysis of the energy-averaged isoscalar monopole double transition density and strength functions over a broad energy range including the isoscalar giant monopole resonance and its overtone in the {sup 208}Pb nucleus.
