Theory of (d,p) and (p,d) reactions including breakup: Comparison of methods

Abstract

There is an increasing interest in studying transfer reactions to probe the nuclear structure of exotic nuclei.

Adiabatic approximation versus exact Faddeev method for (d,p) and (p,d) reactions

“…We will focus the discussion on the reaction A(d,p)B to the ground state (g.s.) of B = n + A (note that the formalism for (p,d) in prior form is identical to that for (d,p) in post form presented here [17]). Following the work on the zero-range ADWA [6], Johnson and Tandy [7] introduced a full finite range version considering the square-integrable Sturmian expansion.…”

“…The three-body wavefunction Eq. (4) is now inserted in the post-form T-matrix for the (d,p) process [17]:…”

“…[15]), the CDCC wavefunction has also been used in the context of (d,p) reactions (e.g. [16,17]). The AGS method including the Coulomb interaction, originally developed for describing few-nucleon reactions [18], has recently been extended to handle (d,p) and (p,d) nuclear reactions [19].…”

Improved description ofAr34,36,46(p,d) transfer reactio

“…In the last couple of decades, with the advances of rare isotope facilities, it has been possible to explore shell structure away from stability and perhaps expectedly, new orbital ordering, level occupancies and magic numbers have been revealed (e.g. the doubly magic 24 O [2]). In this quest of understanding shell evolution as one moves toward the limits of stability, nuclear reactions have played a central role.…”

“…Examples include the study of optical potential uncertainties [20], the effect of the reaction mechanism [21], the uncertainties in the single particle state [22,23], the description of the deuteron continuum [24] and the inclusion of full three-body dynamics in the reaction [25].…”
