Experimental Probe to the Isospin-Dependent Properties of Hot
Nuclei in Reactions 40Ar+112,124Sn at 30 MeV/u
Abstract： Protons are emitted much more affluently in neutron-deficient system 40Ar+112Sn while triton emissions are greater in a neutron-rich system 40Ar+124Sn at incident energy of 30 MeV/u. Similar to neutron, proton emission provied a dominant contribution to neutralize the system N/Z in the decay process of the hot nuclei. The emission of hydrogen isotopes with high energies is much enhanced in the 112Sn system. The original temperature of the hot nuclei in the 40Ar+112Sn reaction is 5.8±0.3 MeV, about 0.7 MeV higher than 5.1±0.3 MeV as in the 40Ar+124Sn reaction.
