Abstract. Nuclear halos emerge as new degrees of freedom near the neutron and proton driplines. They consist of a core and one or a few nucleons which spend most of their time in the classically-forbidden region outside the range of the interaction. Individual nucleons inside the core are thus unresolved in the halo configuration, and the low-energy effective interactions are short-range forces between the core and the valence nucleons. Similar phenomena occur in clusters of 4 He atoms, cold atomic gases near a Feshbach resonance, and some exotic hadrons. In these weakly-bound quantum systems universal scaling laws for s-wave binding emerge that are independent of the details of the interaction. Effective field theory (EFT) exposes these correlations and permits the calculation of non-universal corrections to them due to short-distance effects, as well as the extension of these ideas to systems involving the Coulomb interaction and/or binding in higher angular-momentum channels. Halo nuclei exhibit all these features. Halo EFT, the EFT for halo nuclei, has been used to compute the properties of single-neutron, two-neutron, and single-proton halos of s-wave and p-wave type. This review summarizes these results for halo binding energies, radii, Coulomb dissociation, and radiative capture, as well as the connection of these properties to scattering parameters, thereby elucidating the universal correlations between all these observables. We also discuss how Halo EFT's encoding of the long-distance physics of halo nuclei can be used to check and extend ab initio calculations that include detailed modeling of their short-distance dynamics.arXiv:1702.08605v2 [nucl-th] 5 Nov 2017 EFT for halo nuclei 2

“…In fact the long-range behavior of Coulomb interaction gives rise to severe singularities in the kernel of the integral equation that the latter may lack the compactness property known to exist in the case of purely short-range interactions. One way of dealing with this problem is to use the screening and renormalization method [3,5] which has successfully described not only the 3-body but also 4-body nuclear systems [6][7][8][9][10]. Unfortunately, the technical difficulties arise in the renormalization procedure as the charge of the target increases making this approach is unreliable for targets with charge 28 Z [11].…”

The amplitude of the triangular diagrams in the three-body models of deuteron induced reactions with charged particles contains the off-shell two-body T-matrix describing the intermediate-state Coulomb scattering of charged subsystems. Up to now the latter has usually been replaced by the Coulomb potential due to the computational reason. In this paper, we first investigate theoretically and numerically the validity of the mentioned Coulomb-Born approximation. The results show the important contribution of the higher order of the latter approximation for the (d,p) reactions off heavy target.

“…However the sensitivities to the model space and input parameters are generally not the same. The Faddeev method [13] has recently been applied to (d,n) [14]. As pointed out in that work, (d,n) represented different challenges to (d,p), particularly concerning the handling of the Coulomb through screening.…”

“…As pointed out in that work, (d,n) represented different challenges to (d,p), particularly concerning the handling of the Coulomb through screening. In [14] only light targets were considered and the aim was mostly to establish whether the Faddeev method could indeed reproduce the existing (d,n) data.…”

Examining the effect of nonlocality in(d,n)transfer reactions

Background: In the last year we have been exploring the effect of the explicit inclusion of nonlocality in (d,p) reactions.Purpose: The goal of this work is to extend previous studies to (d,n) reactions, which, although similar to (d,p), have specific properties that merit inspection.Method: We apply our methods (both the distorted wave Born approximation and the adiabatic wave approximation) to (d, n) reactions on 16 O, 40 Ca, 48 Ca, 126 Sn, 132 Sn, and 208 Pb at 20 and 50 MeV. Results:We look separately at the modifications introduced by nonlocality in the final bound and scattering states, as well as the consequences reflected on the differential angular distributions. The cross sections obtained when using nonlocality explicitly are significantly different than those using the local approximation, just as in (d,p). Due to the particular role of Coulomb in the bound state, often we found the effects of nonlocality to be larger in (d,n) than in (d,p). Conclusions:Our results confirm the importance of including nonlocality explicitly in deuteron induced reactions.
