Nuclear Physics Seminar with Jaclyn Schmitt on Probing Spin-Isospin Excitations in Proton-Rich Nuclei

Jaclyn Schmitt (Hosted by Piarulli) from Michigan State University will be presenting the seminar "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 Î²-Gamow-Teller transition strengths, B(GT), 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 the shell model and ab-initio methods. This is the first time that the (p,n) probe in inverse kinematics has been used with beams of unstable proton-rich nuclei, and the feasibility of using this probe to study heavier isotopes up to the 100Sn region during the FRIB era will also be discussed.
