Neutron spectroscopic factors from transfer reactions

Abstract

In the present paper, we examine past measurements of ground state to ground state ($d,p$) and ($p,d$) transfers that were performed on targets with $Z=3--24$. We describe a procedure that we utilized to extract a consistent set of spectroscopic factors. Most of the 80 spectroscopic factors that we extracted are in good agreement with large-basis shell model predictions. We evaluate the consistency of this method by comparing the spectroscopic factors obtained separately in ($p,d$) and ($d,p$) reactions. For nuclei for which Endt has compiled values, our results and those of Endt are strongly correlated. We apply our method to more reactions and more nuclei than Endt had, and our comparisons between spectroscopic factors obtained in ($d,p$) and ($p,d$) reactions display more consistency than the corresponding comparisons in Endt.
