Fragmentation of hot quantum drops

Journal Article · · Phys. Rev. C; (United States)
Statistical and quantum dynamical expansion calculations for finite and hot quantum drops are performed. Quantum dynamical evolution trajectories are calculated and compared with static equation of state calculations. Density distributions are studied and evidence for volume dependent multifragmentation processes is obtained for most breakup temperatures. The breakup trajectories in the T,rho plane fluctuate below the critical values of the equation of state results. Small as well as large fragments are found in U-shape spectra. At temperatures above the breakup temperature the quantum drops vaporize and at temperatures below the breakup temperature the hot drops evaporate some nucleons. For averaged initial densities of the order of equilibrium density, matter does not fragment near the critical point. Thus, it appears unlikely that the multifragmentation phenomenon can be used to study the isothermal critical region of liquid-vapor phase transitions.
