Constraining the density dependence of the symmetry energy from nuclear masses / B.K. Agrawal, D. J. N., S.K. Samaddar, G. Colò, A. Sulaksono. - In: PHYSICAL REVIEW. C, NUCLEAR PHYSICS. - ISSN 0556-2813. - 87:5(2013), pp. 051306.1-051306.5. [10.1103/PhysRevC.87.051306]
Abstract:
Empirically determined values of the nuclear volume and surface symmetry
energy coefficients from nuclear masses are expressed in terms of
density distributions of nucleons in heavy nuclei in the local density
approximation. This is then used to extract the value of the symmetry
energy slope parameter L. The density distributions in both spherical
and well deformed nuclei calculated within microscopic framework with
different energy density functionals give L = 59.0 +/- 13.0 MeV.
Application of the method also helps in a precision determination of the
neutron skin thickness of nuclei that are difficult to measure
accurately.
