Mean-field description of fusion barriers with Skyrmeʹs interaction Original Research Article

Fusion barriers are determined in the framework of the Skyrme energy-density functional together with the semi-classical approach known as the Extended Thomas–Fermi method. The barriers obtained in this way with the Skyrme interaction View the MathML source turn out to be close to those generated by phenomenological models like those using the proximity potentials. It is also shown that the location and the structure of the fusion barrier in the vicinity of its maximum and beyond can be accurately described by a simple analytical form depending only on the masses and the relative isospin of target and projectile nucleus.
