Abstract
The expansion velocity profile in central heavy-ion reactions in the Fermi energy domain is examined. The radial expansion is non-Hubblean and in the surface region it scales proportional to a higher exponent of the radius. The anomalous expansion velocity profile is accompanied by a power-law nucleon density profile in the surface region. Both these features of central heavy-ion reactions disappear at higher energies, and the system follows a uniform Hubble expansion
