Reactions induced by 9Be in a four-body continuum-discretized coupled-channels framework
(Springer Nature, 2015-06-01)
We investigate the elastic scattering of 9Be on 208Pb at beam energies above (50MeV) and below (40MeV) the Coulomb barrier. The reaction is described within a four-body framework using the Continuum-Discretized Coupled-Channels ...

Experimental study of 6He + 9Be elastic scattering at low energies
(American Physical Society, 2011)
New data for the H6e+9Be reaction at Elab=16.2 and 21.3 MeV have been taken and analyzed. The effect of the collective couplings to the excited states of the target has been studied by means of coupled-channels calculations, ...

Three-body nuclei and their astrophysical implications: The case of 6He
(American Institute of Physics, 2013)
The analytic THO method [1] is generalized to study three-body nuclei of astrophysical interest, and applied to 6He. Results are consistent with previous publications and experimental data [2, 3].

Be 9 elastic scattering on Pb 208 and Al 27 within a four-body reaction framework
(American Physical Society, 2015)
We investigate low-energy Be9 elastic scattering on two different targets (heavy, light) within a four-body framework using the continuum-discretized coupled-channels (CDCC) method. The Be9 projectile is described in an ...

Astrophysical reaction rate for 9 Be formation within a three-body approach
(American Physical Society, 2014)
The structure of the Borromean nucleus 9Be (α+α+n) is addressed within a three-body approach using the analytical transformed harmonic oscillator method. The three-body formalism provides an accurate description of the ...

Elastic scattering, inelastic excitation, and 1 n pick-up transfer cross sections for 10 B + 120 Sn at energies near the Coulomb barrier
(American Physical Society, 2018)
The 10 B + 120 Sn reaction has been systematically studied at laboratory energies around the Coulomb barrier: E LAB = 31.5 , 33.5, 35.0, and 37.5 MeV. Cross sections for the elastic scattering and some reaction ...

Be 9 + Sn 120 scattering at near-barrier energies within a four-body model
(American Physical Society, 2018)
Cross sections for elastic and inelastic scattering of the weakly bound Be9 nucleus on a Sn120 target have been measured at seven bombarding energies around and above the Coulomb barrier. The elastic angular distributions ...

Determining astrophysical three-body radiative capture reaction rates from inclusive Coulomb break-up measurements
(American Physical Society, 2016-04-12)
A relationship between the Coulomb inclusive break-up probability and the radiative capture reaction rate for weakly bound three-body systems is established. This direct link provides a robust procedure to estimate the ...

Improved di-neutron cluster model for 6 He scattering
(American Physical Society, 2007)
The structure of the three-body Borromean nucleus He6 is approximated by a two-body di-neutron cluster model. The binding energy of the 2n-α system is determined to obtain a correct description of the 2n-α coordinate, as ...

Analytical transformed harmonic oscillator basis for three-body nuclei of astrophysical interest: Application to 6He
(American Physical Society, 2013-06-29)
Recently, a square-integrable discrete basis, obtained performing a simple analytical local scale transformation to the harmonic oscillator basis, has been proposed and successfully applied to study the properties of ...
