Pairing Correlations in Halo Nuclei
Paring correlations in weakly bound halo nuclei He and Li are studied by using a threebody model with a density-dependent contact interaction. We investigate the spatial structure of two-neutron wave function in a Borromean nucleus Li. The behavior of the neutron pair at different densities is simulated by calculating the two-neutron wave function at several distances between the core nucleus L...

متن کاملPairing and shell gaps in nuclei
The pairing contribution to the odd-even oscillations in the nuclear binding energies is considered in the framework on the nuclear shell model. Schematic and realistic Hamiltonians are used to understand the trends related to pairing and shell gaps. Detailed results are shown and discussed for the calcium isotopes. Results are also shown for carbon, oxygen and neon as well as the overall trend...
متن کاملSome New Perspectives on Pairing in Nuclei
Ever since the work of Richardson in the mid-60s1, it has been recognized that the Pairing Model (PM) is exactly solvable, even in the presence of non-degenerate single-particle levels. In recent years, there has been a resurgence of interest in the PM, with several applications reported that build on this exact solvability 2. This talk reviews two recent applications of the PM in nuclear physi...
متن کاملMixed-spin pairing condensates in heavy nuclei.
We show that the Bogoliubov-de Gennes equations for nuclear ground-state wave functions support solutions in which the condensate has a mixture of spin-singlet and spin-triplet pairing. We find that such mixed-spin condensates do not occur when there are equal numbers of neutrons and protons, but only when there is an isospin imbalance. Using a phenomenological Hamiltonian, we predict that such...
