Coupling of shape and pairing vibrations in a collective Hamiltonian based on nuclear energy density functionals
Coupling of shape and pairing vibrations in a collective Hamiltonian based on nuclear energy density functionals
The quadrupole collective Hamiltonian, based on relativistic energy density functionals, is extended to include a pairing collective coordinate. In addition to quadrupole shape vibrations and rotations, the model describes pairing vibrations and the coupling between shape and pairing degrees of freedom. The parameters of the collective Hamiltonian are determined by …
