Description
The ground-state properties of nuclei can be described within the liquid-drop model, where nuclear stability against deformation is governed by the competition between the surface energy and the Coulomb energy. The Coulomb interaction also plays an essential role in spontaneous fission. Motivated by these considerations, we focus on nuclear deformation and Coulomb effects in finite nuclei. To quantify Coulomb contributions to nuclear structure, we perform systematic calculations of even–even nuclei within nuclear density functional theory. We then examine how Coulomb effects manifest in microscopic observables, with particular emphasis on the evolution of canonical single-particle energies as visualized in Nilsson diagrams.
