准自由反应对束缚态重叠函数细节的敏感性

Sensitivity of quasi-free reactions on details of the bound-state overlap functions

C. A. Bertulani, A. Idini, C. Barbieri

摘要:

人们常说,重离子核子敲除反应对束缚态波函数的尾部非常敏感。与此相反,(p,2p)和(p,pn)反应被认为可以获得原子核内完全重叠函数的信息。我们分析了氧同位素链,并探讨了单粒子波函数与潜在的模型,用于敲除反应的实验分析,从头计算从自洽格林函数理论产生的差异。与普遍的看法相反,我们发现,不仅尾部的重叠功能,而且其内部的一部分进行评估,在这两个反应机制,这是至关重要的,以产生准确确定的光谱信息。

英文摘要:

It is often stated that heavy-ion nucleon knockout reactions are mostly sensitive to the tails of the bound-state wavefunctions. In contrast, (p,2p) and (p,pn) reactions are known to access information on the full overlap functions within the nucleus. We analyze the oxygen isotopic chain and explore the differences between single-particle wave functions generated with potential models, used in the experimental analysis of knockout reactions, and ab initio computations from self-consistent Green's function theory. Contrary to the common belief, we find that not only the tail of the overlap functions, but also their internal part are assessed in both reaction mechanisms, which are crucial to yield accurately determined spectroscopic information.
