Abstract：
The charged particles and residues were correlatively measured by telescopes and PPACs in the reaction of ⁴⁰Ar+⁹³Nb at incident energy of 25 MeV/u. Energy spectra of αparticles were fitted by three moving sources and the excitation energy of hot nuclei were determined by the TOF of residues and particle multiplicity. Abstracted temperature was correlated thoroughly and the results show that hot nuclei with excitation energy E/A≈4.3MeV and temperature T_init≈6.9MeV were formed in the reaction The behavior of nuclear matter in various systems was compared and the difference can be seen in the light and heavy reaction system.
