Probing Spin-Isospin Excitations in Proton-Rich Nuclei via the (p,n) Reaction*

Tracking the evolution of nuclear properties away from stability serves as a valuable test for nuclear models. In the present work, the (p,n) charge-exchange reaction is used to test the extraction of β^- GT strengths and other nuclear structure information from proton-rich unstable isotopes. The ¹¹C(p,n)¹¹N reaction was measured in inverse kinematics at 100 MeV/A at the National Superconducting Cyclotron Laboratory (NSCL). The extracted B(GT) will be compared to results from mirror ¹¹B(n,p)-type reactions and to predictions of theoretical models. Progress of the analysis for this experiment will be presented. This experiment is the first time the (p,n) probe has been used on the proton-rich side of the nuclear chart, and the feasibility of using this probe to study heavier isotopes up to the ¹⁰⁰Sn region during the FRIB era will also be discussed.
