在R^{3}B/LAND装置上，采用准自由单质子敲除反应，在300-450 MeV/u的入射束流能量范围内，系统地研究了稳定氧同位素和奇异氧同位素的结构。氧同位素链提供了一个很大的变化的分离能，使单粒子强度与变化的同位旋不对称性的定量理解。准自由敲除反应为中能单核子去除反应提供了一种补充方法。计算了^{A}O（p，2 p）^{A-1}N型准自由敲除反应的包含截面，并与程函反应理论的计算结果进行了比较.相对于独立粒子模型的单粒子强度的减少因子，并比较国家的最先进的从头算预测。结果没有显示出任何显着的依赖质子-中子不对称性。
Quasifree one-proton knockout reactions have been employed in inverse kinematics for a systematic study of the structure of stable and exotic oxygen isotopes at the R^{3}B/LAND setup with incident beam energies in the range of 300-450 MeV/u. 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 one-nucleon removal reactions. Inclusive cross sections for quasifree knockout reactions of the type ^{A}O(p,2p)^{A-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 asymmetry.
