4. HISTORICAL BACKGROUND AND INFORMATION

The LLNL Evaluated Nuclear Data Library has existed since 1958 in a succession of forms and formats. The present form is as a machine-independent character file format and contains data for the evaluated atomic relaxation data library (EADL), the evaluated photon interaction data library (EPDL), and the evaluated electron interaction data library (EEDL). In October 1997, EPDL89 was replaced with EPDL97; and the Evaluated Excitation Data Library (EXDL) was added to the package. For user convenience, the photon interaction cross sections in ENDF-6 format were also added to the package.

5. APPLICATION OF THE DATA

The purpose of these libraries is to furnish data for coupled electron-photon transport calculations. In order to perform coupled photon-electron transport calculations, all three libraries are required. The UCRL-50400, Vol. 6, Rev. 5 and UCRL-ID-117796 reports included in the documentation for this package provide information on the contents and formats for the libraries which are included in this package. The CCC-638/TART96 code package is recommended for use with these data. Codes within TART96 can be used to display these data or to run calculations using these data.

6. SOURCE AND SCOPE OF DATA

All of these libraries span atomic numbers, Z, from 1 to 100. Additionally the electron and photon interaction libraries cover the incident particle energy range from 10 eV to 100 GeV. EPDL97 includes data down to 1eV.

7. DISCUSSION OF THE DATA RETRIEVAL PROGRAM

SCATMAN reads photon interaction cross sections in the ENDL character format and calculates anomalous scattering factors and/or coherent cross sections. It is designed to be both a research code to investigate the effect of various assumptions and approximations and as a production code to be used to produce data for inclusion in the EPDL.

RELAX calculates atom relaxation spectra of X-rays and electrons due to bound-bound transitions. This calculation is based on the atomic transition data contained in EADL.

Both codes are written in Fortran 77 and run on VAX and other computers. See comments in source files following 'COMPUTER DEPENDENT CODING'. Comments included in the source files provide the latest descriptive information and input instructions. Program CONVERT may be used to automatically convert this program back and forth using any combination of these computer dependent options.

8. DATA FORMAT AND COMPUTER

ASCII card images; transmitted as a UNIX tar file. The ENDF/B-VI photon interaction library is based upon the LLNL evaluated photon data library (EPDL) and is included in this package in file PHOTB6. As yet ENDF/B does not have formats to handle electron interaction or atomic relaxation parameters. Therefore, at the current time the complete set of three data libraries is only available in the ENDL type format.
