Detailed characterization of neutron-proton equilibration in dynamically deformed nuclear systems

We study neutron-proton equilibration in dynamically deformed nuclear systems by investigating the correlations between the two largest fragments produced in collisions of Zn-70 + Zn-70, Zn-64 + Zn-64, Ni-64 + Ni-64 and Zn-64 + Ni-64 at 35 MeV per nucleon. The extent of equilibration is investigated using the rotation angle as a clock for the equilibration. The initially dissimilar fragments converge exponentially with consistent rate constants across a wide variety of reaction partners and systems, indicating that the equilibration follows first-order kinetics.
