ENSDF - The evaluated nuclear structure data file

Abstract A file on nuclear structure and decay data, ENSDF, has been implemented as a set of ADABAS files at the Fachinformationszentrum Energie, Physik, Mathematik in Karlsruhe. NATURAL and ASSEMBLER program packages have been developed for the on-line presentation of the data. Problems encountered in representing large floating point numbers and the inherent hierarchy of the data are discussed.
