摘要：

Charged product multiplicities and Z distributions were measured for single multifragmenting sources produced in collisions between Xe-129 + Sn-nat and Gd-155 + U-238 at the same available energy per nucleon. Z distributions are found identical for both reactions while fragment multiplicities scale as the charge of the total systems. A complete dynamical simulation, in which multifragmentation originates in the spinodal decomposition of a finite piece of nuclear matter resulting from an incomplete fusion of projectile and target, well accounts for this experimental observation.
