Dynamic polarization in the Coulomb breakup of loosely bound 17F

Angular distributions of the Coulomb breakup of radioactive F-17 were measured by impinging a 10 MeV/nucleon beam on Pb-208 and on Ni-58 to study the dynamic polarization effects. The breakup products, oxygen and a proton, were detected in coincidence. First-order perturbation theory significantly overpredicts the breakup cross section for the Pb-208 target. Dynamical calculations with a dynamic polarization as the leading order correction were performed. The calculations reproduce the data for F-17 oil Ni-58 but overpredict the breakup of F-17 on Pb-208 by a factor of two at forward angles. (C) 2009 Elsevier B.V. All rights reserved.
