AI 中文摘要
我们介绍一个新的Python包FETA，用于计算裂变观测量。与市场上现有的裂变事件建模代码相比，FETA是一个模块化、灵活且与代码无关的封装器，围绕一个统计反应理论程序构建。在本文中，我们报告FETA的2.0版本，该版本使用LLNL开发的Hauser-Feshbach代码YAHFC模拟碎片的瞬发衰变。我们讨论FETA的设计理念，展示对239Pu中子诱发裂变的验证结果，并简要概述该包的结构。
英文摘要
We present a new Python package called FETA to compute fission observables. In comparison to existing fission event modeling codes on the market, FETA is a modular, flexible, and code-agnostic wrapper around a statistical reaction theory program. In this paper, we report on version 2.0 of FETA, which simulates the prompt decay of the fragments with the LLNL-developed Hauser-Feshbach code YAHFC. We discuss the design philosophy of FETA, present some validation results for the neutron-induced fission of 239Pu, and briefly outline the structure of the package.
