不同反应探针提取的光谱因子的不对称依赖性的差异引起了相应的反应模型是否被正确理解的问题。在本工作中，我们提出了提取光谱因子的Ar 46，34（p，d）Ar 45，33转移反应的逆运动学在束流能量为70 MeV/核子。结果与先前在较低束能量下对这些反应的测量一致[Lee等人，物理修订信函104，112701（2010）]，表明转移反应是在宽能量范围内探测奇异核的核结构的可靠探针。从一个大的身体的转移反应测量，（p，p N）的测量结果，和理论核结构的研究，使一个令人信服的情况下，弱得多的不对称性的依赖比观察到的单核子敲除反应铍或碳目标。
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 Ar 46 , 34 ( p , d ) Ar 45 , 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 , p N ) 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.
