Nuclear disassembly into light and intermediate mass ejectiles is searched for in 40Ar + 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.
