In intermediate-mass systems, collective excitations of the target and projectile can greatly enhance the subbarrier capture cross section σcap by giving rise to a distribution of Coulomb barriers. For such systems, capture essentially leads directly to fusion [formation of a compound nucleus (CN)], which then decays through the emission of light particles (neutrons, protons, and alpha particles). Thus, the evaporation-residue (ER) cross section is essentially equal to σcap. For heavier systems… Expand
