Isospin Diffusion in Heavy-Ion Collisions and the Neutron Skin Thickness of Lead

Andrew W. Steiner, Bao-An Li

Published 2005-05-17, updated 2005-10-12Version 2

The correlation between the thickness of the neutron skin in Pb-208, and the degree of isospin diffusion in heavy-ion collisions is examined. The same equation of state is used to compute the degree of isospin diffusion in an isospin-depedent transport model and the neutron skin thickness in the Hartree-Fock approximation. We find that skin thicknesses less than 0.15 fm are excluded by the isospin diffusion data.
