Reactions Induced by $$^9$$ 9 Be in a Four-Body Continuum-Discretized Coupled-Channels Framework

Abstract

We investigate the elastic scattering of 9 Be on 208 Pb at beam energies above (50 MeV) and below (40 MeV) the Coulomb barrier. The reaction is described within a four-body framework using the Continuum-Discretized Coupled-Channels (CDCC) method. The 9 Be projectile states are generated using the analytical Transformed Harmonic Oscillator (THO) basis in hyperspherical coordinates. Our calculations confirm the importance of continuum effects at low energies.
