反对称、几何不变的多核子理论中d+A系统的三体模型
Three-body model of the d+A system in an antisymmetrised, translationally invariant many nucleon theory
摘要:
本文讨论了A(d,p)B直接反应的理论,以及它们的实用三体模型与描述氘核组分与靶A相互作用的光学模型势的关系。本文提出了核子光学势的一个新的定义,它要求仔细研究伴随耦合道问题所涉及的边界条件。新的定义证明是方便的,使(d,p)反应的理论的联系。分析是在反对称的,conventionally不变的形式主义,并提供了坚实的基础,从多体的角度来看,在以前的工作中计算的三体力的影响Dinmore,Al-Khalili和约翰逊。
英文摘要:
This paper concerns the theory of direct A(d,p)B reactions and how practical 3-body models of them are related to optical model potentials describing the interaction of the deuteron's constituents and the target A. A new definition of the nucleon optical potential is introduced which necessitates a careful examination of the boundary conditions involved in the associate coupled channels problem. The new definition turns out to be convenient for making a connection with the theory of the (d,p) reaction. The analysis is carried out within an antisymmetrised, translationally invariant formalism and provides a firm basis from a many-body point of view for the three-body force effects calculated in previous work by Dinmore, Timofeyk, Al-Khalili and Johnson.
