The role of transfer in fusion reactions is studied within the framework of a microscopic model. In the case of the 40Ca+40Ca reaction, the coupling to transfer channels is essentially adiabatic and explains about one third of the observed enhancement over unrenormalized potential barrier estimates. Taking into account the excitation of low-lying vibrations in the adiabatic approximation brings theory in overall agreement with the data. Predictions for transfer processes are also presented which can be used to further discriminate between the potentials.

Abstract
The role of transfer in fusion reactions is studied within the framework of a microscopic model. In the case of the 40Ca+40Ca reaction, the coupling to transfer channels is essentially adiabatic and explains about one third of the observed enhancement over unrenormalized potential barrier estimates. Taking into account the excitation of low-lying vibrations in the adiabatic approximation brings theory in overall agreement with the data. Predictions for transfer processes are also presented which can be used to further discriminate between the potentials.File in questo prodotto:
