Proton-neutron pairing and binding energies of nuclei close to N=Z line
D. Negrea, N. Sandulescu, D. Gambacurta
We analyse the contribution of isovector and isoscalar proton-neutron pairing to the binding energies of even-even nuclei with and atomic mass . The bindin…
Structure of the quartetting ground state of nuclei
A. G. Serban, D. R. Nichita, D. Negrea +1
The formal equivalence between the quartetting picture and the symmetry restored BCS picture is established for the ground state correlations induced by the general isovector-isosc…
Bridging the quartet and pair pictures of isovector proton-neutron pairing
V. V. Baran, D. R. Nichita, D. Negrea +3
The formal implications of a quartet coherent state ansatz for proton-neutron pairing are analyzed. Its nonlinear annihilation operators, which generalize the BCS linear quasiparti…
Isovector and isoscalar proton-neutron pairing in nuclei
D. Negrea, P. Buganu, D. Gambacurta +1
We propose a particle number conserving formalism for the treatment of isovector-isoscalar pairing in nuclei with . The ground state of the pairing Hamiltonian is described by…
Isovector and isoscalar pairing in odd-odd nuclei within a quartet approach
D. Negrea, N. Sandulescu, D. Gambacurta
The quartet condensation model (QCM) is extended for the treatment of isovector and isoscalar pairing in odd-odd N=Z nuclei. In the extended QCM approach the lowest states of isosp…
Proton-neutron pairing in N=Z nuclei: quartetting versus pair condensation
N. Sandulescu, D. Negrea, D. Gambacurta
The isoscalar proton-neutron pairing and isovector pairing, including both isovector proton-neutron pairing and like-particle pairing, are treated in a formalism which conserves ex…
