Abstract
By using point-coupling versions of finite-range nuclear relativistic mean-field models containing cubic and quartic self-interactions in the scalar field , a nonrelativistic limit is achieved. This approach allows an analytical expression for the symmetry energy as a function of its slope in a unified form, namely, , where the quantities , and are bulk parameters at the nuclear matter saturation density . This result establishes a linear correlation between and which is reinforced by exact relativistic calculations. An analogous analytical correlation is also found for , and the symmetry energy curvature . Based on these results, we propose graphic constraints in and planes that finite-range models must satisfy.
