论文摘要
分解反应是研究松散结合的核的最受欢迎的探针之一，尤其是在稳定性极限形成光环的核心的核心中。为了解释这种分解实验，通常使用连续离散的耦合通道方法。在这项研究中，进行了第一个对分解反应模型的贝叶斯分析。我们将统计方法与三体反应模型（连续离散的耦合通道方法）结合在一起，以量化分手可观测值的不确定性，这是由于有效潜在的参数，描述了有效势能，这些参数描述了较宽的弹丸。我们开发的工具的组合为贝叶斯分析不仅为分解过程提供了一条路径，而且还为需要计算强化反应模型的各种复杂过程。
Breakup reactions are one of the favored probes to study loosely bound nuclei, particularly those in the limit of stability forming a halo. In order to interpret such breakup experiments, the continuum discretized coupled channel method is typically used. In this study, the first Bayesian analysis of a breakup reaction model is performed. We use a combination of statistical methods together with a three-body reaction model (the continuum discretized coupled channel method) to quantify the uncertainties on the breakup observables due to the parameters in the effective potential describing the loosely bound projectile of interest. The combination of tools we develop opens the path for a Bayesian analysis of not only breakup processes, but also a wide array of complex processes that require computationally intensive reaction models.
