Title: Mass chain evaluations for the evaluated nuclear structure data file (ENSDF) - an urgent appeal for European participation.

Abstract

Reliable nuclear structure and decay data represent the fundamental building blocks of nuclear physics and astrophysics research, and are also of vital importance in a significant number of applied nuclear fields such as power generation and associated fuel cycle operations (e.g., fuel manufacture, transport, reprocessing, and waste management), materials analysis, medical diagnosis, and radiotherapy. There is a continuous demand for good quality data formulated and recommended through the speedy assessment and incorporation of new and improved measurements.

  • The structure, organization, and contents of the Evaluated Nuclear Structure Data File, ENSDF, will be discussed. This file summarizes the state of experimental nuclear structure data for all nuclei as determined from consideration of measurements reported world wide. Special emphasis will be given to the data evaluation procedures and consistency checks utilized at the input stage and to the retrieval capabilities of the system at the output stage.
  • Graphical comparisons of recently obtained experimental beta-ray spectra with predicted beta-ray spectra based on the Evaluated Nuclear Structure Data File are exhibited for 77 fission products having masses 79--99 and 130--146 and lifetimes between 0.17 and 23650 sec. The comparisons range from very poor to excellent. For beta decay of 47 nuclides, estimates are made of ground-state transition intensities. For 14 cases the value in ENSDF gives results in very good agreement with the experimental data. 12 refs., 77 figs., 1 tab.
  • The main purpose of this study is to develop a unified plan to provide users with on-line access to numeric nuclear structure data and provide, in a people readable format, information not published in Nuclear Data Sheets.
  • The Evaluated Nuclear Structure Data File (ENSDF), is maintained by the National Nuclear Data Center (NNDC) on behalf of the international Nuclear Structure and Decay Data (NSDD) network organized under the auspices of the International Atomic Energy Agency. ENSDF provides evaluated experimental nuclear structure and decay data for basic and applied research. The activities of the NSDD network, the publication of the evaluations, and their use in different applications are described. Since 1986, the ENSDF and related numeric and bibliographic data bases have been made available for on-line access. The current status of these data bases, and future plans tomore » improve the on-line access to their contents are discussed. 8 refs., 4 tabs.« less
