Abstract
The elastic scattering and breakup reactions of the halo nucleus Be11 on deuterons at an incident energy of 26.9A MeV are reported for the first time. Special attention has been paid to the determination and subtraction of the proton contaminations in the deuterated polyethylene (CD2)n target (where D2 denotes H22). The cross sections for elastic scattering are analyzed with the systematic optical potentials of Daehnick et al. and DA1p, as well as with single-folding potentials, derived from the Jeukenne-Lejeune-Mahaux effective nucleon-nucleon interaction. An extended version of the continuum-discretized coupled-channels (XCDCC) formalism, including dynamic core excitation (DCX) effects, is applied to analyze the elastic scattering and breakup data. Comparisons of the full XCDCC calculation with that omitting DCX effects indicate that the core excitation plays a remarkable role in reproducing breakup reactions of Be11+d.1 MoreReceived 31 August 2016DOI:https://doi.org/10.1103/PhysRevC.94.064620©2016 American Physical SocietyPhysics Subject Headings (PhySH)Research AreasBreakup reactionsDirect reactionsLow & intermediate energy heavy-ion reactionsNuclear reactionsUnstable nuclei induced nuclear reactionsProperties6 ≤ A ≤ 19Nuclear Physics
