Decay by proton emission from high-lying states in Nb91, populated in the Zr90(α,t) reaction at Eα=180 MeV, has been investigated. Decay to the ground state and semidirect decay to the low-lying (2+,5-, and 3-) phonon states in Zr90 were observed. It was found that these phonon states play an important role in the damping process of the single-particle states. An optical-model coupled-channel approach was used successfully to describe the direct and semidirect parts of the decay.
