The 6He Optical Potential at energies around the Coulomb barrier
(American Institute of Physics, 2010)
We present an Optical Model (OM) study of 6He on 208Pb elastic scattering data, measured at laboratory energies around the Coulomb barrier (Elab=14, 16, 18, 22, and 27 MeV) [1]. For the projectile-target bare interaction, ...

Core excitations in the structure and reactions of halo nuclei
(EDP Sciences, 2014-03-20)
We analyse the resonant break-up of halo nuclei including possible excitations of the core both in the structure of the halo nucleus and in the reaction dynamics. The structure of the halo nucleus is treated in the ...

Particle motion in a deformed potential using a transformed oscillator basis
(American Physical Society, 2012)
The quantum description of a particle moving in a deformed potential is investigated. A pseudostate (PS) basis is used to represent the states of the composite system. This PS basis is obtained by diagonalizing the system ...

DHalo nuclei follow rutherford elastic scattering at energies below the barrier? the case of 11Li
(American Physical Society, 2012-12-26)
The first measurement of the elastic scattering of the halo nucleus 11Li and its core 9Li on 208Pb at energies near the Coulomb barrier is presented. The 11Li+208Pb elastic scattering shows a strong reduction with respect ...

Description of the 11Li(p,d)10Li transfer reaction using structure overlaps from a full three-body model
(Elsevier, 2017)
Recent data on the differential angular distribution for the transfer reaction 11Li(p,d)10Li at E/A=5.7 MeV in inverse kinematics are analyzed within the DWBA reaction framework, using the overlap functions calculated ...

Numerical assessment of post-prior equivalence for inclusive breakup reactions
(American Physical Society, 2015)
We address the problem of the post-prior equivalence in inclusive breakup reactions induced by weakly bound nuclei. The problem is studied within the distorted-wave Born approximation (DWBA) model of Ichimura, Austern, ...

Evidence of strong dynamic core excitation in 19C resonant break-up
(American Physical Society, 2016)
The resonant breakup of 19C on protons measured at RIKEN [Y. Satou et al., Phys. Lett. B 660, 320 (2008)] is analyzed in terms of a valence-core model for 19C that includes possible core excitations. The analysis of ...

Comprehensive analysis of large α yields observed in 6Li-induced reactions
(American Physical Society, 2017-04-06)
Background: Large α yields have been reported over the years in reactions with 6 Li and 7 Li projectiles. Previous theoretical analyses have shown that the elastic breakup (EBU) mechanism (i.e., projectile breakup leaving ...

The Research Program at RIBRAS (Radioactive Ion Beams in Brasil)-III
(American Institute of Physics, 2010)
A part of the research program developed in the RIBRAS facility over the last four years is presented. Experiments using radioactive secondary beams of light exotic nuclei such as 6He, 7Be, 8Li on several targets have ...

Extracting three-body breakup observables from continuum-discretized coupled-channels calculations with core excitations
(American Physical Society, 2017)
Core-excitation effects in the scattering of two-body halo nuclei have been investigated in previous works. In particular, these effects have been found to affect in a significant way the breakup cross sections of neutron-halo ...
