A consistent four-body CDCC model of low-energy reactions: Application to 9Be+208Pb

We investigate the 9Be+208Pb elastic scattering, breakup and fusion at energies around the Coulomb barrier. The three processes are described simultaneously, with identical conditions of calculations. The 9Be nucleus is defined in an α + α + n three-body model, using the hyperspherical coordinate me...

Summary:We investigate the 9Be+208Pb elastic scattering, breakup and fusion at energies around the Coulomb barrier. The three processes are described simultaneously, with identical conditions of calculations. The 9Be nucleus is defined in an α + α + n three-body model, using the hyperspherical coordinate method. We first analyze spectroscopic properties of 9Be, and show that the model provides a fairly good description of the low-lying states. The scattering with 208Pb is then studied with the Continuum Discretized Coupled Channel (CDCC) method, where the α + α + n continuum is approximated by a discrete number of pseudostates. Optical potentials for the α+208Pb and n+208Pb systems are taken from the literature. We present elasticscattering and fusion cross sections at different energies.
