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.
