| 英文摘要 | The experimental liquid-gas phase transition signals are examined for the quasiprojectile (QP) reconstructed from the reactions of Ar-40 + Al-27, Ti-48, Ni-58 at 47 MeV/nucleon, using measures of caloric curve, multiplicity derivative, moment parameters, and fluctuation of maximum fragment charge number (NVZ). The QP source is reconstructed, using moving source parametrizations on an event-by-event basis. For the determination of the temperature, a quadrupole fluctuation thermometer is used. Deuterons are chosen for the thermometer to minimize the Coulomb and secondary sequential decay effects. A new event-by-event method is proposed for the thermometer to determine the temperature. All measures show a characteristic signature around the temperature T = 9.0 +/- 0.4 MeV, which may suggest that the QP system goes into the liquid-gas phase transition at T-c = 8.3 +/- 0.4 MeV after the Coulomb correction. |
