Abstract

A discrepancy in the asymmetry dependence of spectroscopic factors extracted with different reaction probes calls into question whether the corresponding reaction models are properly understood. In this work, we present extracted spectroscopic factors from the Ar46,34(p,d)Ar45,33 transfer reactions in inverse kinematics at a beam energy of 70 MeV/nucleon. The results are consistent with previous measurements of these reactions at a lower beam energy [Lee et al., Phys. Rev. Lett. 104, 112701 (2010)], indicating that the transfer reaction is a reliable probe for the nuclear structure of exotic nuclei across a wide energy range. Results from a large body of transfer reaction measurements, (p,pN) measurements, and theoretical nuclear structure studies make a compelling case for much weaker asymmetry dependence than what is observed with single-nucleon knockout reactions on beryllium or carbon targets.Received 19 June 2020Revised 9 November 2020Accepted 8 June 2021DOI:https://doi.org/10.1103/PhysRevC.104.024608©2021 American Physical SocietyPhysics Subject Headings (PhySH)Research AreasDirect reactionsModels & methods for nuclear reactionsNuclear reactionsSpectroscopic factors & electromagnetic momentsTransfer reactionsNuclear Physics
