Reactions with weakly-bound exotic nuclei using deformed two-body models

The $^{11}$Be halo nucleus has been studied using different deformed two-body models, the Nilsson model and the semi-microscopic PAMD model. Electric transition probabilities have been calculated with both models and found to be compatible with those extracted from Coulomb dissociation data. The calculated $B(E1)$ and $B(E2)$ are applied to the calculation of $^{11}$Be+$^{208}$Pb Coulomb dissociation cross section. Both models reproduce reasonably well the experimental data. It is also shown that quadrupole resonances are relevant for this agreement, being PAMD model more accurate in the energy of such resonances.
