Balance of Mass, Momentum, and Energy in Splintering Central Collisions for A{sup 40}r up to 115 MeV/ Nucleon

For central collisions of 17-115 A MeV {sup 40}Ar+Cu , Ag, Au, an overall balance is determined for the average mass, energy, and longitudinal momentum. Light charged particles and fragments are separated into forward-focused and isotropic components in the frame of the heaviest fragment. Energy removal by the isotropic component reaches 1-2 GeV. For such high deposition energies, statistical multifragmentation models predict much more extensive nuclear disassembly than is observed. (c) 1999 The American Physical Society.
