Radiative capture reaction for Ne 17 formation within a full three-body model
(American Physical Society, 2016)
Background: The breakout from the hot Carbon-Nitrogen-Oxigen (CNO) cycles can trigger the rp-process in type I x-ray bursts. In this environment, a competition between 15O(α,γ )19Ne and the two-proton capture reaction 15O(2p,γ ...

Description of continuum structures in a discrete basis: Three-body resonances and two-nucleon decays
(SciPost, 2020)
Weakly bound and unbound three-body nuclei are studied by using the pseudostate method within the hyperspherical formalism. After introducing the theoretical framework, the method is applied first to the 9Be nucleus, ...

9Be scattering within a four-body continuum-discretized coupled-channels framework
(EDP Sciences - SIF, 2016-05-11)
The scattering of 9Be on 208Pb is addressed within a four-body Continuum-Discretized Coupled-Channels (CDCC) framework, considering a three-body α + α + n projectile plus a structureless target. The projectile states are ...

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 ...

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 ...

Four-body continuum-discretized coupled-channels calculations using a transformed harmonic oscillator basis
(The American Physical Society, 2008)
The scattering of a weakly bound three-body system by a target is discussed. A transformed harmonic oscillator basis is used to provide an appropriate discrete and finite basis for treating the continuum part of the spectrum ...

Continuum coupling in one-dimensional scattering using a transformed harmonic oscillator basis
(American Physical Society, 2002)
The continuum coupling in a one-dimensional scattering problem was studied within a semiclassical approach by means of a transformed harmonic oscillator (THO). The THO basis provided a finite set of normalized states ...

Probing 6He structure from proton inelastic collisions
(American Institute of Physics, 2006)
We explore the Hyperspherical Harmonics pseudostate method to describe the 6He continuum. The method is use it within the multiple scattering of the transition amplitude (MST) approach to study inelastic scattering of p-6He ...

Comment on "from Coulomb Excitation Cross Sections to Nonresonant Astrophysical Rates in Three-body Systems: The Ne 17 Case"
(American Physical Society, 2020)
Parfenova et al. state in [Phys. Rev. C 98, 034608 (2018)2469-998510.1103/PhysRevC.98.034608] that the results presented by Casal et al. [Phys. Rev. C 94, 054622 (2016)2469-998510.1103/PhysRevC.94.054622] concerning the ...
