9Be scattering within a four-body continuum-discretized coupled-channels framework

Abstract

The scattering of 9Be on 208Pb is addressed within a four-body Continuum-Discretized Coupled-Channels (CDCC) framework, considering a three-body α + α + n projectile plus a structureless target. The projectile states are generated using the analytical Transformed Harmonic Oscillator (THO) basis in hyperspherical coordinates. Both the elastic and breakup channels are described on the same footing. We find a good agreement between our calculations and the experimental data at beam energies around and below the Coulomb barrier.
