Statistical origin of complex particles in intermediate energy heavy ion reactions

Part of the Lecture Notes in Physics book series (LNP, volume 263)


The compound nucleus mechanism for complex fragment emission is discussed theoretically and demonstrated experimentally. The role of the potential energy as a function of mass asymmetry is shown in experimental charge distributions. This process is followed from near the threshold up to bombarding energies of several tens of MeV A.
