Abstract：
For the reaction of 25MeV/u ⁴⁰Ar with ¹⁹⁷Au, coincidence measurements have been made for the heavy residue fission fragments and light charged particles (Z≤2). The folding-angle and time of flight of heavy residue fission fragments were used to deduce the linear momentum transfer (LMT). The initial properties of these nuclei, excitation energies, angular momenta and temperatures, have been studied by measurements of LMT and light particle spectra. The relation between the excitation energy per nucleon and temperature is analysed by different windows of LMT. It is shown that the hot nuclei are close to saturation of temperature for central collision and close to "phase transition for multifragmentation".
