核反应实验数据库(EXFOR)

The Experimental Nuclear Reaction Data(EXFOR)

核反应实验数据库(EXFOR)及其检索系统提供了丰富的中低能核反应物理信息和数据,已经成为国际上最全面的核反应实验数据汇编。目前,由国际原子能机构核数据科(IAEA/NDS)协调管理,国际核反应数据中心协作网(NRDC)13个成员进行全球性合作,旨在协调国际范围内核反应实验数据的收集、编纂和传播。中国核数据中心(CNDC)作为NRDC成员之一,多年来开展了大量的中子和带电粒子引起的核反应实验测量和建库技术研究。本文介绍了EXFOR数据库的形成、发展和现况,以及数据格式、数据编纂和检索系统,并简要总结了我国核反应实验数据建库及技术研究等方面的工作,如国内期刊检索、EXFOR数据库文档建设、程序开发、国内数据服务及国际合作等。

The EXchange FORmat(EXFOR)experimental nuclear reaction database and the retrieval system provide access to the wealth of low-and intermediate-energy nuclear reaction physics data,and become the most comprehensive compilation of experimental nuclear reaction data.Currently,there are 13 participants(nuclear data centers)of the International Network of Nuclear Reaction Data Centers(NRDC)which has been organized under the auspices of the International Atomic Energy Agency(IAEA)to coordinate the collection,compilation,and dissemination of nuclear data on an international scale.As the participant of NRDC,China Nuclear Data Center(CNDC)does its best for measurement of nuclear reaction quantities induced by neutron and chargedparticle and research on the technique of database construction.The formation,development and current situation of EXFOR library,and its format,compilation and retrieval system were introduced.The work on compilation of experimental nuclear reaction data and study of the database construction technique in China was briefly summarized,such as scanning Chinese journals,compiling EXFOR entries,developing software,providing nuclear data service in China,collaborating with NRDC and so on.
