Abstract
For central collisions of (17-115)A MeV Ar-40 + Cu, Ag, Au, an overall bala nce is determined for the average mass, energy, and longitudinal momentum. Light charged particles and fragments are separated into forward-focused an d isotropic components in the frame of the heaviest fragment. Energy remova l by the isotropic component reaches 1-2 GeV. For such high deposition ener gies, statistical multifragmentation models predict much more extensive nuc lear disassembly than is observed.
