Beyond the coherent coupled channels description of nuclear fusion

Dasgupta, Mahananda; Diaz-Torres, Alexis; Bouriquet, Bertrand; Low, Catherine; Milburn, Gerard James; Newton, J; Hinde, David


New measurements of fusion cross sections at deep sub-barrier energies for the reactions 16O+204,208Pb show a steep but almost saturated logarithmic slope, unlike 64Ni-induced reactions. Coupled channels calculations cannot simultaneously reproduce these new data and above-barrier cross-sections with the same Woods-Saxon nuclear potential. It is argued that this highlights an inadequacy of the coherent coupled channels approach. It is proposed that a new approach explicitly including gradual...[Show more]
