摘要：

The effect of the coupling to a resonant state in one of the partners of a heavy-ion fusion reaction on the fusion cross section is discussed. We conclude that the width of the resonance could either enhance or hinder the fusion, depending on the relative importance of the spreading to escape widths. General comments on the fusion of neutron-rich nuclei are made.
