Pairing Matrix Elements and Pairing Gaps with Bare, Effective and Induced Interactions
The dependence on the single-particle states of the pairing matrix elements of the Gogny force and of the bare low-momentum nucleonnucleon potential vlow−k designed so as to reproduce the low-energy observables avoiding the use of a repulsive core is studied in the semiclassical approximation for the case of a typical finite, superfluid nucleus (120Sn). It is found that the matrix elements of v...
متن کاملIsospin-Dependence of π/π Ratio and Density-Dependence of Nuclear Symmetry Energy
The π/π ratio is examined as a function of isospin asymmetry and beam energy for central collisions induced by neutron-rich nuclei within an isospindependent hadronic transport model. The π/π ratio is found to increase with the isospin asymmetry, but decrease with the beam energy of the reaction. For neutron-rich systems, such as, Sn + Sn and Sn + Sn, the sensitivity of π/π ratio to nuclear sym...
متن کاملDependence of the 1S0 superfluid pairing gap on nuclear interactions
Nucleon-nucleon (NN) interactions are well constrained for relative momenta k 2 fm−1 by existing scattering data [1]. The model dependences for larger momenta can be seen, for instance, in the P2 superfluid pairing gaps for Fermi momenta kF > 2 fm−1 [2]. In Ref. [3], we study in detail the dependence of the S0 superfluid gap on nuclear interactions at the BCS level, and on the resolution scale....
متن کاملIsospin dependence of the spin-orbit force and effective nuclear potentials.
The isospin dependence of the spin-orbit potential is investigated for an effective Skyrme-like energy functional suitable for density dependent Hartree-Fock calculations. The magnitude of the isopin dependence is obtained from a fit to experimental data on finite spherical nuclei. It is found to be close to that of relativistic Hartree models. Consequently, the anomalous kink in the isotope sh...
