Constraining the symmetry energy at subsaturation densities using isotope binding energy difference and neutron skin thickness

We show that the neutron skin thickness Δrnp of heavy nuclei is uniquely fixed by the symmetry energy density slope L(ρ) at a subsaturation cross density ρc≈0.11 fm−3 rather than at saturation density ρ0, while the binding energy difference ΔE between a heavy isotope pair is essentially determined b...
