翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Nuclear data ： ウィキペディア英語版 Nuclear data Nuclear data represents measured (or evaluated) probabilities of various physical interactions involving the nuclei of atoms. It is used to understand the nature of such interactions by providing the fundamental input to many models and simulations, such as fission and fusion reactor calculations, shielding and radiation protection calculations, criticality safety, nuclear weapons, nuclear physics research, medical radiotherapy, radioisotope therapy and diagnostics, particle accelerator design and operations, geological and environmental work, radioactive waste disposal calculations, and space travel calculations It groups all experimental data relevant for nuclear physics and nuclear applications. It includes a large number of physical quantities, like scattering and reaction cross sections (which are generally functions of energy and angle), nuclear structure and nuclear decay parameters, etc. It can involve neutrons, protons, deuterons, alpha particles, and virtually all nuclear isotopes which can be handled in a laboratory. There are two major reasons to need high-quality nuclear data: theoretical model development of nuclear physics, and applications involving radiation and nuclear power. There is often an interplay between these two aspects, since applications often motivate research in particular theoretical fields, and theory can be used to predict quantities or phenomena which can lead to new or improved technological concepts. ==Nuclear Data Evaluations== To ensure a level of quality required to protect the public, experimental nuclear data results are occasionally ''evaluated'' by a Nuclear Data Organization to form a standard nuclear data library. These organizations review multiple measurements and agree upon the highest-quality measurements before publishing the libraries. For unmeasured or very complex data regimes, the parameters of nuclear models are adjusted until the resulting data matches well with critical experiments. The result of an evaluation is almost universally stored as a set of data files in Evaluated Nuclear Data File (ENDF) format. To keep the size of these files reasonable, they contain a combination of actual data tables and resonance parameters that can be reconstructed into pointwise data with specialized tools (such as NJOY). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Nuclear data」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
