  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.
