Breakup dynamic polarization potential for 6He+208Pb at 27 MeV

Mackintosh, R.S. and Keeley, N. (2004). Breakup dynamic polarization potential for 6He+208Pb at 27 MeV. Physical Review C, 70(2, Article)



We study the local dynamic polarization potential, DPP, component of the 6He+208Pb interaction generated by the coupling to breakup channels as calculated using the continuum-discretized coupled-channels (CDCC) method. The results are for 6He at a laboratory energy of 27 MeV. The elastic channel S-matrix is inverted and the bare potential of the CDCC calculation is subtracted to yield the DPP. This has a very long attractive and absorptive tail, with the real component extending beyond 40 fm, generated by Coulomb breakup. Although the long tail of the DPP has a major effect on the elastic S-matrix, it is shallow enough to have a more modest effect on the root mean square (rms) radius (increased) and the volume integrals. To facilitate comparison with other theories, the potential tails are fitted to analytic forms.
