Abstract
A two-step-reaction model calculation based on projectile fragmentation (first step), preequilibrium emission, and evaporation emission (second step) is formulated to describe the particle-particle angular correlations and particle-γ correlations in complex-projectile-induced reactions. The model gives a good description of the production of fast projectilelike α particles accompanied by incomplete fusion for reactions Gd160 (C12,αxn)168x Er at four incident energies.
