Investigation of the nuclear liquid-gas phase transition in the static AMD

Nuclear liquid-gas phase transitions are investigated in the framework of static antisymmetrized molecular dynamics (static AMD) model under either a constant volume or pressure. A deuteron quadrupole momentum fluctuation thermometer is applied to extract temperature fragmenting systems $^{36}$Ar and $^{100}$Sn. plateau structure caloric curves observed for those system with density $\rho \leq$ 0.03 fm$^{-3}$. clear backbending curves, which indicates first order transition, pressure all pressures studied. The similar behavior $^{100}$Sn that there no strong size effect Both mass distributions light particle multiplicities show $\alpha$ clusterization at low excitation energies AMD simulations. transition measures multiplicity derivative (dM/dT) normalized variance $Z_{max}$ (NVZ) applied. experimental also compared simulations both conditions. Discussions presented available results from Large errors measurements reconstruction technique primary source hinder draw conclusion whether occurs This study suggests different should be examined besides conclusion.
