摘要

Data for the C-13(Li-6, t)O-16 reaction, obtained in inverse kinematics at a C-13 incident energy of 7.72 MeV, are presented. A distorted wave Born approximation (DWBA) analysis was used to extract spectroscopic factors and asymptotic normalization coefficients (ANCs) for the O-16 vertical bar C-13 + He-3 overlaps, subject to the assumption of a fixed Li-6 vertical bar He-3 + H-3 overlap. The variation of the extracted spectroscopic factors and ANCs as a function of various inputs to the DWBA calculations was explored. The extracted ANCs were found to vary as a cubic function of the radius of the potential well binding the transferred He-3 to the C-13 core while the spectroscopic factors varied as a quartic function of the radius. The ANC values could be determined to within a factor of two for this system.
