摘　　要：氘核削裂反应作为单核子转移反应的一种,在原子核的单粒子结构研究中一直起着重要的作用。同时,作为典型的三体核反应,它也是直接核反应理论研究的一个重要研究对象。本文简述了氘核削裂反应的研究历史,侧重介绍其反应理论的演进,以及平面波玻恩近似(Plane Wave Born Approximation,PWBA)、扭曲波玻恩近似(Distorted Wave Born Approximation,DWBA)、连续态离散化耦合道理论(Continuum Discretized Coupled Channels,CDCC)、绝热波近似理论(Adiabatic Wave Approximation,ADWA)和法捷耶夫方程组(Faddeev equations)方法之间的差别与联系。本文讨论了当前及未来氘核削裂反应理论研究的若干热点问题,包括中高能条件下的氘核削裂反应、转移到剩余核连续态的理论、色散光学势以及非定域光学势在氘核削裂反应中的应用等。本文展示了我们对中高能条件下的氘核削裂反应理论计算的一些初步成果。As one type of single nucleon transfer reactions,deuteron stripping reaction has been playing an important role in the study of the single particle structure of atomic nuclei.Also,as a typical three-body nuclear reaction,deuteron stripping reaction is also an important subject in the development of direct nuclear reaction theories.We briefly review the history of the study of deuteron stripping reactions,focusing on the evolution of its theoretical descriptions,and the differences and the relations of the Plane Wave Born Approximation(PWBA),the distorted wave Born approximation(DWBA),the Continuum Discretized Coupled Channel method(CDCC),the Adiabatic Wave Approximation(ADWA),and the approach based on the Faddeev equations.Some important problems being currently addressed in deuteron stripping reaction theories and those should be addressed in near future are also discussed,including deuteron strippings at intermediate and high energies,theory for transfer to continuum states of the residue nuclei,applications of dispersive optical model potentials and non-local potentials,etc.Some preliminary results of our theoretical calculations for deuteron stripping at intermediate and high energies are presented.
