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, ...

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 ...

Three-body radiative capture reactions
(EDP Sciences, 2017)
Radiative capture reaction rates for 6He, 9Be and 17Ne formation at astrophysical conditions are studied within a three-body model using the analytical transformed harmonic oscillator method to calculate their states. An ...

Understanding 6He induced reactions at energies around the Coulomb barrier
(American Institute of Physics, 2009)
Recent developments aimed to understand the observed features arising in the scattering of the Borromean nucleus 6He on heavy targets are discussed and compared with recent data for 6He+208Pb measured at the RIB facility ...

Four-body continuum-discretized coupled-channels calculations: Application to 6He+64Zn at 13.6 MeV
(American Institute of Physics, 2009)
The recently developed four-body continuum-discretized coupled-channels (CDCC) method, making use of the binning procedure [1], is applied to the reaction 6He+64Zn at 13.6 MeV (around the Coulomb barrier). Excellent agreement ...

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 ...

Three-body continuum discretization in a basis of transformed harmonic oscillator states
(American Physical Society, 2005-01-01)
The inclusion of the continuum in the study of weakly bound three-body systems is discussed. A transformed harmonic oscillator basis is introduced to provide an appropriate discrete and finite basis for treating the ...
