En International Scientific Meeting on Nuclear Physics - Basic Concepts in Nuclear Physics: Theory, Experiments, and Applications (152-153), La Rábida: American Institute of Physics.978-073541165-40094-243X1551-7616https://hdl.handle.net/11441/84399A recent generalization of the Transformed Harmonic Oscillator basis, intended to consider core excitations in the structure of one nucleon halo nuclei, is applied to the break up of 11Be. The reaction studied is 11Be+208Pb at 69 MeV/nucleon. The experimental set up is designed to ensure pure dipole Coulomb excitations. Making use of the Equivalent Photon Method and the electromagnetic transition probabilities obtained with the transformed oscillator basis, a relevant contribution of the quadrupole excitations of the core is found. The inclusion of core excitations is, therefore, necessary for the correct extraction of the dipole electromagnetic transition probability of halo nuclei.application/pdfengAttribution-NonCommercial-NoDerivatives 4.0 Internacionalhttp://creativecommons.org/licenses/by-nc-nd/4.0/Nuclear reactionsHalo nucleiBreakupCore excitationinfo:eu-repo/semantics/conferenceObjectinfo:eu-repo/semantics/openAccess10.1063/1.4810823
