The oxygen isotopic chain offers a large variation of separation energies that allows for a quantitative understanding of single-particle strength with changing isospin asymmetry. Quasifree knockout reactions provide a complementary approach to intermediate-energy onenucleon removal reactions. Inclusive cross sections for quasifree knockout reactions of the type AOðp; 2pÞA−1 N have been determined and compared to calculations based on the eikonal reaction theory. The reduction factors for the single-particle strength with respect to the independent-particle model were obtained and compared to state-of-the-art ab initio predictions. The results do not show any significant dependence on proton-neutron asymmetryengCreative Commons Attribution 4.0 International license.http://creativecommons.org/licenses/by-nc-nd/4.0/Direct reactionsNuclear reactionsNuclear sturcture & decaysShell modeljournal article10.1103/PhysRevLett.120.0525011079-7114open access
