Slope-dependent nuclear-symmetry energy within the effective-surface approximation

  title={Slope-dependent nuclear-symmetry energy within the effective-surface approximation},
  author={Jacek Błocki and A. G. Magner and Peter Ring},
  journal={Physical Review C},
The effective-surface approximation is extended taking into account derivatives of the symmetry-energy density per particle with respect to the mean particle density. The isoscalar and isovector particle densities in this extended effective-surface approximation are derived. The improved expressions of the surface symmetry energy, in particular, its surface tension coefficients in the sharp-edged proton-neutron asymmetric nuclei take into account important gradient terms of the energy density…

Semiclassical approaches to nuclear dynamics
The extended Gutzwiller trajectory approach is presented for the semiclassical description of nuclear collective dynamics, in line with the main topics of the fruitful activity of V.G. Solovjov.
Shells, orbit bifurcations, and symmetry restorations in Fermi systems
The periodic-orbit theory based on the improved stationary-phase method within the phase-space path integral approach is presented for the semiclassical description of the nuclear shell structure,
Minimal nuclear energy density functional
We present a minimal nuclear energy density functional (NEDF) called "SeaLL1" that has the smallest number of possible phenomenological parameters to date. SeaLL1 is defined by 7 significant


Nuclear Models: Collective and Single-Particle Phenomena
This third enlarged and revised edition incorporates seven extensive new chapters on the general collective model for low-energy modes and many changes in text figures, tables and references where experimental ortheoretical developments over the past two decades have brought about new information and understanding.
