摘要

The systematic quenching of spectroscopic factors in terms of separation energy asymmetry in single-nucleon knockout reactions remains a puzzle for two decades. We propose a core screening effect due to a finite-sized probe, considering the suppression when deeply bound nucleons in the projectile nucleus are removed by the heavy-ion target. The core screening effect is simulated as a medium modification of single-particle wave functions inside the projectile. This work shows that the parameterized screening effect can explain the isospin dependence of quenching factors, offering insights into reaction mechanisms between two composite quantum systems.
