AI总结:

本文综述Gogny唯象有效相互作用的起源、历史演变及当前挑战,涵盖参数化确定、模拟器拟合、核物质作用及其在核结构、裂变和反应中解释实验数据的成果。

AI中文摘要:

本综述文章的主要目标是有史以来首次汇集唯象有效Gogny相互作用的各种面貌,该相互作用最初于70年代提出。这既涉及导致其创建和演化的相关核现象,也涉及使目标得以实现的高度技术性方面。基于此,我们提出围绕四个要点进行讨论。在一般性引言之后,阐述了Gogny相互作用的历史和哲学。特别地,我们强调了一种直观的方法,即利用Hartree-Fock计算、二阶修正和G矩阵从现实相互作用获得的结果来指导唯象相互作用参数的确定。我们还表明,配对或裂变等物理现象对于改进参数化至关重要。还讨论了原始解析形式多年来的演变。第二个要点涉及用于生成参数化的模拟器。给出了其与解析形式演变相一致的修改。还提到了其他更近期的拟合程序。第三个关键点专门讨论核物质在拟合过程和参数化接受中的作用。最后一个关键点的目的是突出展示利用Gogny相互作用在核结构、裂变和反应中获得的一些结果,这些结果使得解释实验数据成为可能。

英文摘要:

In the present review, various facets of the phenomenological effective Gogny interaction, which was originally proposed in the 70's, are gathered for the first time in the same place. This involves both nuclear phenomena of interest that led to its creation and evolution as well as highly technical aspects that led the objectives to be achieved. With this in mind, a discussion structured around four key points is proposed. After a general introduction, the history and philosophy of the Gogny interaction is exposed. In particular, one highlights the way followed by D. Gogny to guide the determination of the parameters of its phenomenological interaction with results obtained from a realistic interaction using Hartree-Fock calculations and second order corrections and a G-matrix. One also shows how physical phenomena such as pairing or fission were essential to improve the initial parameterization. The evolution of the original analytical form over the years is then discussed. The second key point concern the emulator that was used for the generation of parameterizations. Its modifications, consistent with the evolution of its analytical form along the decades, are detailed. Other fitting procedures from other groups, more recent, are also evoked. The third key point is dedicated to the role of some nuclear matter properties in the fitting process and the acceptance of a parameterization. The objective of the last key point consists in highlighting some results obtained with the Gogny interaction in various domains such as nuclear structure, fission, reactions and nuclear data that have allowed to interpret many experimental data. Perpsectives are given explaining some paths that will be followed in the future concerning the functional itself as well as N-body approaches.
