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 ...

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 ...

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 ...
