Use of Neutron Transfer Reactions to Indirectly Determine Neutron Capture Cross Sections on Neutron-Rich Nuclei

Abstract

14C(n,γ)15C is being used as a test case in the development of an indirect method to determine neutron capture cross sections on neutron‐rich unstable nuclei at astrophysical energies. Our approach makes use of two reactions: one peripheral used to find the asymptotic normalization coefficient (ANC) and a second non‐peripheral reaction to determine the spectroscopic factor. The ANC for 15C has been determined using a HI neutron transfer reaction with a 12 MeV/nucleon 14C beam on a 13C target. The spectroscopic factor will be determined using 14C(d,p) in forward kinematics with an incident deuteron energy of 60 MeV. Both experiments were performed using the MDM high‐resolution spectrometer at Texas A&M University.
