  We develop a statistical approach for the description of complex nuclei
formation from dynamically produced baryons in high energy heavy-ion reactions.
We consider a finite highly-excited expanding nuclear system formed after
central nucleus-nucleus collisions. This system is sub-divided into primary
equilibrated nucleon clusters. The final nuclei are produced after the decay of
these excited clusters. By the successful comparison with the FOPI experimental
data we prove the possibility of such a local equilibrium in nuclear matter
with the temperature corresponding to the phase coexistence region. The
regularities obtained in this new nuclei production mechanism are shown.
