New determination of the proton spectroscopic factor in Be-9 from the C-13 (Be-9, Li-8) N-14 angular distribution

The 13 C( 9 Be, 8 Li) 14 N angular distribution was measured with a 9 Be beam of 40 MeV. The proton spectroscopic factor of the 9 Be ground state was extracted to be 0.73 ± 0.15 by the normalization of the calculated differential cross sections with the distorted-wave Born approximation (DWBA) to the experimental data. The spectroscopic factor was compared to existing theoretical and experimental values
