    "abstract": "We accurately analyze the $^6$He+$^{209}$Bi scattering at 19 and 22.5 MeV\nnear the Coulomb barrier energy, using the continuum-discretized\ncoupled-channels method (CDCC) based on the $n$+$n$+$^4$He+$^{209}$Bi four-body\nmodel.\n  The three-body breakup continuum of $^6$He is discretized by diagonalizing\nthe internal Hamiltonian of $^6$He in a space spanned by the Gaussian basis\nfunctions.\n  The calculated elastic and total reaction cross sections are in good\nagreement with the experimental data, while the CDCC calculation based on the\ndi-neutron model of $^6$He, i.e., the $^2n$+$^{4}$He+$^{209}$Bi three-body\nmodel, does not reproduce the data.",
