Abstract:
This contribution discusses a new perception of the structure of compound nuclei by introducing intermediate states of the Feshbach formalism of nuclear reactions in the Interacting Boson Model of nuclear structure. The stake is to explore the manifestation of the unitary limit in heavy, even-even nuclei. Interactions that govern Feshbach resonances of cold and dilute atomic gases suggest the formulation of an IBM-compound Hamiltonian for scattering two neutrons (2 n ) from a heavy, even-even target ( A ). The solutions of the corresponding coupled channel equations host a 2 n -IBM state resonance. It turns out that the unitary limit is measurable in a heavy A + 2 n compound nucleus at low temperatures. That measurement is feasible through the fluctuations of the cross-sections that tune the 2 n - A scattering length.
