Abstract
The connection between the characteristic features of reactions involving very heavy target-projectile combinations (e.g.86Kr+197Au) and lighter systems (e.g.40Ar+natAg) is discussed. Evidence for an empirical scaling law based upon the ratioE/B (center-of-mass kinetic energy to Coulomb barrier) is presented. This scaling is justified in terms of semiquantitative arguments whereby the different charge and angular distribution patterns from light and heavy target-projectile combinations are correlated with different lifetime regimes for the “intermediate complex” as it diffuses along the mass-asymmetry coordinate.
