[P10.006] Surface Symmetry Energy

Pawel Danielewicz (National Superconducting Cyclotron Lab., Michigan State U.)

The symmetry term in the standard binding energy formula has the volume character. However, the description of masses for light nuclei requires the presence of a surface symmetry term in the formula. We analyze nuclear properties in terms of the volume and surface capacitances for asymmetry. The presence of a surface symmetry in the energy implies an existence of the nuclear asymmetry skins describable in terms of a ratio of the volume and surface energy parameters. Using data, we place constraints on the parameters and those imply constraints on the low-density dependence of symmetry energy. Finally, we derive features of the giant isovector resonances in terms of the surface and volume symmetry parameters.
