【 摘 要 】

A major goal of contemporary nuclear physics is to improve our knowledge of the nuclear matter equation of state. In particular, the equation of state of isospin- asymmetric matter (that is, with unequal concentrations of protons and neutrons), is not well understood, mostly due to our limited knowledge of the symmetry energy. The latter reduces the binding energy in a nucleus with unequal number of protons and neutrons, and is crucial for understanding nuclear stability. We review experimental, phenomenological, and theoretical facts about the symmetry energy. We emphasize the importance of adopting a microscopic approach towards a better understanding of this important quantity.
