Symmetry Energy and Surface Clustering in Nuclei; Probing the Asymmetric Nuclear Matter

Abstract

We investigate the properties of asymmetric nuclear matter (ANM) which is consistent with clustering at low densities of nuclear matter. Due to clustering, the equation of state of asymmetric nuclear matter demonstrates peculiar properties. It is shown that the ground of ANM has two separate phases of normal nuclear matter and neutron matter for Z N . This situation is at variance with the conventional picture of uniform distribution of neutrons and protons for ANM. Thus, this leads to an excellent understanding of the symmetry energy data of Wada et al. [1] in the density range of-3 fm 0.032-0.048. It is shown that inclusion of clustering at the nuclear surface is essential to explain about nuclei near the neutron drip line. The research incorporates 2149 nuclei [2] with 8 Z N,  .
