Abstract Deuteron stripping and pick-up experiments - ( d , p ) and ( p , d ) - have been used for a long time to study the structure of nuclei. Today these experiments are often carried out in inverse kinematics in state-of-the-art radioactive beams facilities around the world, extending the boundaries of our knowledge of the nuclear chart. The nuclear structure information obtained from these experiments relies entirely on transfer reaction theory. We review the theory of ( d , p ) and ( p , d ) reactions starting from early formulations and ending with the most recent developments. In particular, we describe the recent progress made in the understanding of the three-body dynamics associated with the deuteron breakup degrees of freedom, including effects of nonlocality, and discuss the role of many-body degrees of freedom within the three-body context. We also review advances in structure model calculations of one-nucleon overlap functions — an important structure input to ( d , p ) and ( p , d ) reaction calculations. We emphasize the physics missing in widely-used standard approaches available to experimentalists and review ideas and efforts aimed at including this physics, formulating the crucial tasks for further development of deuteron stripping and pick-up reaction theory.

用于核结构研究的氘核剥离和提取反应理论

摘要 氘核剥离和拾取实验——(d,p)和(p,d)——长期以来一直被用于研究原子核的结构。今天,这些实验通常在世界各地最先进的放射性束设施中以逆运动学方式进行,从而扩展了我们对核图的了解。从这些实验中获得的核结构信息完全依赖于转移反应理论。我们回顾了 (d, p) 和 (p, d) 反应的理论,从早期的公式开始到最新的发展结束。特别是,我们描述了在理解与氘核分裂自由度相关的三体动力学方面取得的最新进展,包括非定域性的影响,并讨论多体自由度在三体环境中的作用。我们还回顾了单核子重叠函数的结构模型计算的进展——这是 (d,p) 和 (p,d) 反应计算的重要结构输入。我们强调实验者可用的广泛使用的标准方法中缺少的物理学,并回顾旨在包括该物理学的想法和努力,制定进一步发展氘核剥离和拾取反应理论的关键任务。
