Balance of Mass, Momentum, and Energy in Splintering Central Collisions for ${}_{}{}^{40}{}_{}{}^{}Ar$ up to 115 MeV $/$Nucleon

For central collisions of $\left(17–115\right)A\mathrm{MeV}$ ${}^{40}\mathrm{Ar}+\mathrm{Cu}$, 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.
