Area of Science:

  • Nuclear Physics
  • Quantum Many-Body Theory

Background:

  • Accurate description of nuclear properties is crucial for understanding nuclear structure and reactions.
  • Nuclear energy density functionals (EDFs) are essential tools for modeling atomic nuclei.

Purpose of the Study:

  • To investigate the efficacy of a simple local nuclear energy density functional (EDF) in describing nuclear properties.
  • To accurately predict one- and two-nucleon separation energies for semimagic nuclei.

Main Methods:

  • Employed a local nuclear energy density functional (EDF) framework.
  • Utilized previously suggested parametrizations for the normal part of the EDF.
  • Implemented the simplest local form compatible with nuclear symmetries for the superfluid part of the EDF.

  • Demonstrated the capability of the EDF to reproduce key nuclear observables in semimagic nuclei.

Conclusions:

  • A simple local nuclear energy density functional provides an accurate description of nucleon separation energies.
  • The chosen parametrization for the superfluid part is effective and consistent with nuclear symmetries.
