Phys. Rev. Lett. 102, 122502 (2009) [4 pages]Nuclear Symmetry Energy Probed by Neutron Skin Thickness of NucleiReceived 3 June 2008; revised 1 February 2009; published 26 March 2009 We describe a relation between the symmetry energy coefficients csym(ρ) of nuclear matter and asym(A) of finite nuclei that accommodates other correlations of nuclear properties with the low-density behavior of csym(ρ). Here, we take advantage of this relation to explore the prospects for constraining csym(ρ) of systematic measurements of neutron skin sizes across the mass table, using as example present data from antiprotonic atoms. The found constraints from neutron skins are in harmony with the recent determinations from reactions and giant resonances. © 2009 The American Physical Society URL:
