Can spectroscopic informations be extracted from transfer reactions?
We revise the standard method of extracting spectroscopic factors from transfer reactions and show the strong dependence on the single particle parameters. We propose an alternative method applicable whenever there is a significant contribution from the interior to the reaction amplitude while still being well described within Distorted Wave Born Approximation (DWBA). The energies for such reactions should be well above the Coulomb barrier. The alternative method is based on fixing the contribution of the peripheral part of the reaction amplitude, depending on the Asymptotic Normalisation Coefficient (ANC), through another independent totally peripheral reaction. Then, by combining this information with the transfer data above the barrier, one can determine the spectroscopic factor and control the uncertainty coming from the single particle parameters.
