Abstract
Thermodynamic and chemical two-body correlations of the isotope-resolved clusters are measured in reactions at 25 MeV/u. The yield and kinetic variables of the isobars are analyzed in coincidence with the intermediate mass fragments of . While the velocity spectra of both and exhibit scaling behavior over the type of the intermediate mass fragments, the yield ratios of correlate reversely to the neutron-to-proton ratio of the latter, showing the ping-pong modality of the of the emitted particles. The commonality that the of the residues keeps the initial system value is extended to the cluster emission in heavy ion reactions. The comparison to transport model calculations to the data is discussed.
