Abstract

We investigate low-energy Be9 elastic scattering on two different targets (heavy, light) within a four-body framework using the continuum-discretized coupled-channels (CDCC) method. The Be9 projectile is described in an α+α+n three-body model using the analytical transformed harmonic oscillator (THO) basis in hyperspherical coordinates. We show that continuum couplings are important in describing the elastic cross section, especially at low energies and on heavy targets. The dipolar contribution to the elastic cross section at energies around the Coulomb barrier is important but small compared to that of halo nuclei. The effect of the projectile low-energy resonances is also relevant. The agreement with the available experimental data supports the reliability of the method in describing reactions induced by three-body projectiles which include more than one charged particle.
