Breakup of 9Be on 209Bi above and near the Coulomb barrier as a molecular single-particle effect: Its influence on complete fusion and scattering

Abstract The breakup of the 9 Be projectile on the 209 Bi target at bombarding energies above and near the Coulomb barrier is studied in the adiabatic two-center shell model approach. The effect of 9 Be → n +2α breakup channel on complete fusion, elastic and inelastic cross sections is investigated. Results show that the breakup of the projectile 9 Be could be due to a molecular single-particle effect shortly before the colliding nuclei reach the Coulomb barrier.
