Nuclear reaction and structure data services of the National Nuclear Data Center

The mission of the National Nuclear Data Center (NNDC) includes collection, evaluation, and dissemination of nuclear physics data for basic nuclear research and applied nuclear technologies. In 2004, to answer the needs of nuclear data users, NNDC completed a project to modernize storage and management of its databases and began offering new nuclear data Web services. The principles of database and Web application development used at NNDC are described. Examples of nuclear structure, nuclear reaction and bibliographical database applications along with a number of nuclear science tools and codes are presented.
