Liquid-gas phase transition in finite nuclei within Fermionic Molecular Dynamics

Abstract

Within Fermionic Molecular Dynamics (FMD) a quantal nuclear system with only 16 nucleons shows a clearly visible liquid-gas phase transition. The FMD model is an approximation to the many-body problem which describes the system by antisymmetrized many-body states in which each nucleon is occupying a Gaussian shaped time-dependent wave-packet. The statistical ensemble is obtained by time averaging.
