Abstract

In this note, which builds upon our recently published work on an analytical series for the neutron Thermal Scattering Law (TSL), we employ combinatorial methods to reformulate the algebraic series into a more compact form with significantly fewer terms. We demonstrate that this reformulated series offers markedly improved computational efficiency, particularly when evaluating TSL for a large number of energy transfer (β) values. The approach shows good potential for efficient generation of large TSL data in reactor applications.

利用多项组合法快速计算中子热散射定律

本文以我们最近发表的中子热散射定律（TSL）的解析级数为基础，采用组合方法将代数级数重新表述为具有更少项的更紧凑形式。我们证明，这种重新表述的序列显著提高了计算效率，特别是在评估大量能量传递（β）值的TSL时。该方法显示了在反应堆应用中高效生成大型TSL数据的良好潜力。

期刊介绍： Annals of Nuclear Energy provides an international medium for the communication of original research, ideas and developments in all areas of the field of nuclear energy science and technology. Its scope embraces nuclear fuel reserves, fuel cycles and cost, materials, processing, system and component technology (fission only), design and optimization, direct conversion of nuclear energy sources, environmental control, reactor physics, heat transfer and fluid dynamics, structural analysis, fuel management, future developments, nuclear fuel and safety, nuclear aerosol, neutron physics, computer technology (both software and hardware), risk assessment, radioactive waste disposal and reactor thermal hydraulics. Papers submitted to Annals need to demonstrate a clear link to nuclear power generation/nuclear engineering. Papers which deal with pure nuclear physics, pure health physics, imaging, or attenuation and shielding properties of concretes and various geological materials are not within the scope of the journal. Also, papers that deal with policy or economics are not within the scope of the journal.
