TODO - Previous work has quantified the degree of neutron-proton equilibration in heavy-ion nuclear collisions by observing the convergence of isospin observables (such as the isoscaling parameter α) to an expected value based on similar symmetric reaction systems. We present a new signature of equilibration: the convergence of the isospin asymmetry (as quantified by three isoscaling metrics) of two mirror asymmetric reaction systems toward each other rather than a predefined point. For the reactions of 35 MeV/u Zn64,70+Zn64,70 and Zn64,Ni64+Zn64,Ni64 the neutron-proton equilibration was found to be approximately 80%, and this result is compared directly to previous work. © 2018 American Physical Society.
