The relation IBM/PC nuclear structure and decay data base

The Evaluated Nuclear Structure Data File (ENSDF) is now apparently one of the most complete nuclear structure and decay data bank. The most important characteristics from ENSDF are the following: for levels - excitation energy, spin, parity, half-life time, decay branching ratio, electric and magnetic moment; for gamma-transitions -energy, intensity, multipolarity, mixing ratio, for alpha- and beta-decays - energy and itensity. The high frequency personal computers (PC) dissemination, the development of data base management systems (DBMS) with advanced interface and convenient and power required languages allow to put the problem of creation of the universal data base (DB) using the ENSDF information. At bottom the point is in the ENSDF data adaptation to such DBMS in such manner that all possible requests to the ENSDF set to be completely exceeded by the standard resources of DBMS> The data base management system PARADOX (trade mark registered by Borland International) was chosen as a program tool for new universal data base on decay and structure of nuclei.
