本文引入了一个总约化因子（ORF）来研究核子转移反应对单粒子强度的猝灭。ORF包括所有探测的残留核的结合态在转移反应中的贡献，并允许适当的比较与包容性敲除反应的结果。采用Lee等人提出的自洽三体模型反应方法，对原子质量数为8 ~ 56的21个偶偶靶上的103组（p，d）反应的角分布数据进行了系统的分析。（2006年）[25]。提取的ORF被认为是几乎独立的质子-中子不对称性，这是不同的系统的包容性敲除反应，但与最近的测量（d，t），（d，He 3），（p，2 p），和（p，pn）反应的氮和氧同位素和从头计算是一致的。
An overall reduction factor (ORF) is introduced for studying the quenching of single-particle strengths through nucleon transfer reactions. The ORF includes contributions of all the probed bound states of the residual nucleus in a transfer reaction and permits a proper comparison with results of inclusive knockout reactions. A systematic analysis is made with 103 sets of angular distribution data of (p, d) reactions on 21 even–even targets with atomic mass numbers from 8 to 56 using the consistent three-body model reaction methodology proposed in Lee et al.(2006)[25]. The extracted ORFs are found to be nearly independent on the proton–neutron asymmetry, which is different from the systematics of inclusive knockout reactions but is consistent with the recent measurement of (d, t),(d, He 3),(p, 2 p), and (p, p n) reactions on nitrogen and oxygen isotopes and ab initio calculations.
