摘要：Theoretical uncertainties of single proton transfer cross sections of the (3He,d) and (d,3He) reactions
due to the uncertainties of the entrance- and exit-channel optical model potentials are examined with the
30Si(3He,d)31P, 13B(d,3He)12Be, and 34S(3He,d)35Cl reactions at incident energies of 25 MeV, 46 MeV, and
25 MeV, respectively within the framework of distorted wave Born approximation. Differential cross sections
at the first peaks in the angular distributions of these reactions are found to be uncertain within around 5% due
to the uncertainties of the optical model potentials from an result of 20000 times of calculations with the optical
potential parameters randomly sampled. This amount of uncertainties is found to be nearly independent of the
angular momentum transfer and the target masses within the studied range of incident energies. Uncertainties
of the single proton spectroscopic factors obtained by matching the theoretical and experimental cross sections
at different scattering angles are also discussed.
