Abstract
Protons are emitted in a greater quantity in a neutron-deficient system Ar- 40+Sn-112 While triton emissions are greater in a neutron-rich system Ar-40 +Sn-124 at an incident energy of 30 MeV/u. Similar to neutrons, proton emis sion provides a dominant contribution to neutralize the system N/Z in the d ecay process of the hot nuclei. The emission of hydrogen isotopes with high energies is much enhanced in the Sn-112 System. The original temperature o f the hot nuclei in the Ar-40+Sn-112 reaction is 5.8 +/-0.3 MeV, about 0.7 MeV higher than 5.1 +/-0.3 MeV as in the Ar-40+Sn-124 reaction.
