“…The NIMROD 4π array at Texas A&M University [68] was used to study the reactions 64,70 Zn+ 64,70 Zn and 64 Zn, 64 Ni+ 64 Zn, 64 Ni at 35 MeV/u. Details of the setup have been described in refs.…”

“…Two sets of reactions were analyzed. The first reaction set, 64,70 Zn+ 64,70 Zn, compares the cross reactions formed by two different isotopes of zinc, producing a set of reactions that displays an isospin asymmetry difference between projectile and target, with no Coulomb difference between projectile and target. A set of reactions with these properties has also been studied in ref.…”

“…Since the R i was introduced, many studies have continued to probe N-Z equilibration in reactions around the Fermi energy. Experimental [2,6,10,19,21,28,29,50,[60][61][62][63][64] as well as theoretical efforts [26,27,53,65,66] have attempted to place stricter constraints on the asymmetry energy. A recent review [67] concluded that experimental, theoretical, and observational analyses constrain the symmetry parameters S 0 and L to 29.0-32.7 MeV and 40.5-61.9 MeV, respectively.…”

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 towards each other rather than a pre-defined point. For the reactions of 35 MeV/u 64,70 Zn+ 64,70 Zn and 64 Zn, 64 Ni+ 64 Zn, 64 Ni the neutron-proton equilibration was found to be approximately 80%, and this result is compared directly to previous work.
