Phys. Rev. Lett. 80, 5068–5071 (1998)Cooperative Damping Mechanism of the Resonance in the Nuclear PhotoabsorptionReceived 13 November 1997; published in the issue dated 8 June 1998 We propose a resonance damping mechanism to explain the disappearance of the peaks around the position of the resonances higher than the Δ resonance in the nuclear photoabsorption. This phenomenon is understood by taking into account the cooperative effect of the collision broadening of Δ and N*, the pion distortion and the interference in the two-pion photoproduction processes in the nuclear medium. © 1998 The American Physical Society URL:
