摘要
基于多步过程概念建立,可实际应用的核反应统一理论有可能于近年内首先在(n,γ)反应上得以完善。本文结合我们的工作介绍这一领域的进展,按照激发组态中准粒子数这一层次,对(n,γ)反应机制进行分类,并分别讨论每一种反应机制的物理图象、计算公式、模型的特征、验证与实验结果的比较以及有待进一步研究的问题。
It is expected that the unified model of (n, y) reactions based upon the concept of multistep process can be perfected in recent years. The progress made recently in this area is reviewed in this paper. The mechanisms of (n, y) reactions are classified according to the hierarchy of quasiparticle numbers in the excited configurations. For each process, the following questions are discussed: physical significance, schematic representation, calculational formula, test of characteristics that distinguish the mechanism, comparison of theory with data, as well as remaining problems.The present work was supported by the National Science Fundation (China), and International Atomic Energy Agency.
