N2 - We accurately analyze the He6+Bi209 scattering at 19 and 22.5 MeV near the Coulomb barrier energy, using the continuum-discretized coupled-channels (CDCC) method based on the n+n+ He4+Bi209 four-body model. The three-body breakup continuum of He6 is discretized by diagonalizing the internal Hamiltonian of He6 in a space spanned by the Gaussian basis functions. The calculated elastic and total reaction cross sections are in good agreement with the experimental data, whereas the CDCC calculation based on the dineutron model of He6, that is, the 2n+ He4+Bi209 three-body model, does not reproduce the data.
