Nuclear disassembly in violent central collisions at intermediate energies: $\left(65\mathrm{}-115\right)A$ MeV ${}^{40}\mathrm{A}\mathrm{r}+\mathrm{C}\mathrm{u},$ Ag, Au

Nuclear disassembly into light and intermediate mass ejectiles is searched for in ${}^{40}\mathrm{Ar}\mathrm{}+\mathrm{}\mathrm{Cu},$ Ag, Au reactions of $17-115A$ MeV. Distributions in fragment mass versus velocity show that such nuclear disassembly does occur for $65-115A$ MeV. However, it is very rare, with much less abundance than reactions leading to a massive residual nucleus.
