Deuteron- α scattering: Separable versus nonseparable Faddeev approach

Abstract: Background: Deuteron induced reactions are widely used to probe nuclear structure and astrophysical information. Those (d,p) reactions may be viewed as three-body reactions and described with Faddeev techniques.Purpose: Faddeev-AGS equations in momentum space have a long tradition of utilizing separable interactions in order to arrive at sets of coupled integral equations in one variable. However, it needs to be demonstrated that observables calculated based on separable interactions agree exactly with those … Show more

“…Some transfer reactions, such as the important cases of deuteron-induced processes, A + d → (A + 1) + p and A + d → (A + 1) + n, are amenable to description in terms of three inert bodies (A + n + p). The corresponding three-body equations of motion can be integrated exactly within the Faddeev formalism, which recently has been extended to deal with arbitrarily large Coulomb fields as well as with a limited number of excited states of the target (34)(35)(36).…”

“…We adopt the Berggren basis expansion with the "offdiagonal method" [46] to avoid the singularities stemming from the denominator of Green's function and the integration of Coulomb interaction in the asymptotic region [47,48]. Different dynamics of 2p and 2n decays.-For the light 2p emitters, both direct and sequential decays are possible [5,49].…”
