Isospin asymmetric matter behaves differently from symmetric nuclear matter Theoretical Predictions Isospin Equilibration Isospin Fractionation Midrapidity Emission …. Expt Observables Fragment yield dist, Isotopic & isobaric yields, energy spectras ……

Reactions Studied : 124Xe + 112Sn (N/Z) = Sn + 112Sn (N/Z) = Xe + 124Sn (N/Z) = Sn + 124Sn (N/Z) = 1.48 Beam Energy : 28 MeV/ nucleon Detectors : NIMROD, 4  charged particle array

Isospin Dependence of the Fractional Yield Nearly symmetric isotopic yield distribution System with lowest N/Z produce the highest fraction of n-deficient isotopes System with highest N/Z produce highest fraction of n-rich isotopes

Isospin Dependence of Isotopic Yield Ratio and Angular Evolution Angular evolution of isotopic yields depends on the N/Z of the system Isospin equilibration at central angle

Isospin Distillation and Fragment Dependence Excess neutrons become available in the form of light and n-rich clusters Decrease in with increasing Z supports the idea of two phase split of nuclear matter (distillation)

Isospin Dependence of Isobaric Yield Ratios

Energy Spectra Dependence of the Isotopes 3 Source fit for Li fragments

Parallel Velocity Distribution as Function of Centrality

Mid-Rapidity Emission of the Light Fragments

Centrality Dependence of the Relative yield

1.Fractional yield of the n-rich isotopes increase and those of n- deficient isotopes decrease with increasing N/Z of the system. 2.Isotopic and isobaric yield ratios increase linearly with N/Z of the composite system indicating near equilibration along central angle. 3.Neutron content of the light cluster increase significantly with decreasing temperature. 4. of the fragments indicate excess neutrons becoming available to light and n-rich clusters. 5.Energy spectras for different isotopes of light fragments are appreciably different. 6.Rapidity dist. as a function of centrality show heavier isotopes being emitted closer to midrapidity region.
