The Gamow-Teller Giant Resonance in ${}^{11}$Li was measured via the ${}^{11}$Li(p,n)${}^{11}$Be charge-exchange reaction at 182 MeV/u in inverse kinematics at the RIKEN Radioactive Isotope Beam Factory. There is no available data for isovector spin-flip giant resonances in nuclei with large isospin asymmetry factors, where (N−Z)/A > 0.25 [1]. Our work aims to investigate this unexplored region,...

The ${}^{85}$Kr(d,p$\gamma$)${}^{86}$Kr reaction has been carried out at 10 MeV/u in inverse kinematics at Argonne's ATLAS facility using the HELIOS spectrometer and the Apollo array. The neutron capture cross section on the radioisotope ${}^{85}$Kr (T${}_{1/2}$ = 10.7 yr), an s-process branching point nucleus, carries a significant uncertainty due to the challenges of direct measurements. However,...

The rapid (r) neutron-capture process produces half the elements heavier than iron and is located on the neutron-rich side of the nuclear chart. Promising site candidates such as core-collapse supernovae (CCSNe) and neutron star mergers still show large discrepancies between observed and calculated abundances. The calculations mostly rely on theoretical neutron-capture cross sections which...
