209Bi(6He,) reaction mechanisms studied near the Coulomb barrier using n coincidence measurements Academic Article uri icon


  • The 6He+209Bi reaction displays a remarkably large cross section for -particle emission at energies near the Coulomb barrier. The possible reactions that may produce the observed particles include two-neutron transfer, one-neutron transfer, and direct projectile breakup. Each of these mechanisms results in a distinctive angular correlation between the particle and outgoing neutron(s). A neutron--particle coincidence experiment was performed to separate these different modes. The neutron data show significant angular correlations. Monte Carlo simulations of one-neutron transfer are compared with the experimental data. It is shown that approximately 20% of the observed -particle yield is due to this process. 2004 Elsevier B.V.
