ABSTRACT Based on an approach recently proposed by us, simultaneous chi2 analyses are performed for elastic scattering, direct reaction (DR), and fusion cross section data for the 6He+209Bi system at near-Coulomb-barrier energies to determine the parameters of the polarization potential consisting of DR and fusion parts. We show that the data are well reproduced by the resultant potential, which satisfies the proper dispersion relation. A discussion is given of the nature of the threshold anomaly seen in the potential.
