Probing nucleon-nucleon interactions in breakup of a one-neutron halo ${}^{11}$Be on a proton target

Abstract

A comparison between full few-body Faddeev/Alt-Grassberger-Sandhas (Faddeev/AGS) and continuum-discretized coupled channels (CDCC) calculations is made for the resonant and nonresonant breakup of ${}^{11}$Be on proton target at 63.7 MeV/u incident energy. A simplified two-body model is used for ${}^{11}$Be which involves an inert ${}^{10}$Be(0${}^{+}$) core and a valence neutron. The sensitivity of the calculated observables to the nucleon-nucleon potential dynamical input is analysed. We show that with the present NN and N-core dynamics the results remain a puzzle for the few-body problem of scattering from light exotic halo nuclei.
