dc.description.abstract | A novel method to extract the B(E1) strength of a weakly bound nucleus from experimental Coulomb
dissociation data is proposed. The method makes use of continuum discretized coupled channels (CDCC)
calculations, in which both nuclear and Coulomb forces are taken into account to all orders. This is a
crucial advantage with respect to the standard procedure based on the Equivalent Photon Method (EPM)
which does not properly take into account nuclear distortion, higher order coupling effects, or Coulomb-
nuclear interference terms. The systematic and statistical uncertainties of this procedure are evaluated.
The procedure is applied to the 11Be nucleus using two sets of available experimental data at different
energies, for which seemingly incompatible B(E1) have been reported using the EPM. We show that
the present procedure gives consistent B(E1) strengths, thus solving the aforementioned long-standing
discrepancy between the two measurements. | es |
