Description

We accurately analyze the 6He+209Bi 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+ 4He+209Bi four-body model. The three-body breakup continuum of 6He is discretized by diagonalizing the internal Hamiltonian of 6He 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 6He, that is, the 2n+ 4He+209Bi three-body model, does not reproduce the data
