Abstract: Measurements of the density dependence of the free symmetry energy in low density clustered matter have been extended using the NIMROD multi-detector at Texas A&M University. Thermal coalescence models were employed to extract densities, ρ, and temperatures, T, for evolving systems formed in collisions of 47 A MeV {40}Ar + {112}Sn,{124}Sn and {64}Zn + {112}Sn, {124}Sn. Densities of 0.03 ≤ ρ/ρ0 ≤ 0.2 and temperatures in the range 5 to 10 MeV have been sampled. The free symmetry energy coefficients are found to be in good agreement with values calculated using a quantum statistical model. Values of the corresponding symmetry energy coefficient are derived from the data using entropies derived from the model.
