Unbound states in ${}^{19}$O(d,p$\gamma$)${}^{20}$O: tracing the $\nu$(d${}_{3/2}$) orbital

Abstract

The single-neutron transfer reaction ${}^{19}$O(d,p$\gamma$)${}^{20}$O has been performed at GANIL, populating states up to and above the neutron separation energy. Bound states populated by s-wave and d-wave transfer have been observed with improved experimental angular distributions. Critically, several unbound states between 7.6 MeV and 9.8 MeV have been accessed for the first time through the 19O(d,p) channel, and isolated via particle-$\gamma$ spectroscopy.
