Observing the ping-pong modality of the isospin degree of freedom in cluster emission from heavy-ion reactions

NUCLEAR REACTIONS ²⁰⁸Pb(⁸⁶Kr, X), E=25 MeV/nucleon; measured reaction products, A=3 isobars in coincidence with the intermediate mass fragments of A=6-11; deduced velocity spectra of ³H and ³He, yields ratios of ³H/³He correlate reversely to the neutron-to-proton ratio N/Z of the intermediate mass fragments. Comparison with ImQMD transport model. Yield ratio ³H/³He exhibits evident anticorrelation with the N/Z of the latter, suggesting the ping-pong modality of the N/Z of the emitted particles. Anti-correlation shows dependence on the slope of the symmetry energy at saturation density.
