3. DESCRIPTION OF PROGRAM OR FUNCTION

The program has been designed to read the Evaluated Charged Particle Library (ECPL) of the LLNL Evaluated Nuclear Data Library (ENDL) and generate output in various forms: interpreted listing, ENDF format and graphs.

[ top ]

4. METHOD OF SOLUTION

A file containing ECPL in card image transmittal format is scanned to retrieve the requested reactions from the requested materials; in addition selections can be made by data type or incident particle.

[ top ]

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

The Reaction Property Designator I determines the type of data in the ENDL library (e.g. cross sections, angular distributions, Maxwellian averages, etc.); the program does not take into account the data for I=3,4 (energy-angle-distributions) since there are no data in the current ECPL version.

[ top ]

6. TYPICAL RUNNING TIME

A few seconds for a single material on a 15 mips computer.

[ top ]

7. UNUSUAL FEATURES OF THE PROGRAM

The OMICRON code performs graphic output using the BC deck, a FORTRAN package for data display on any device with a very simple interface supplied by the user.

11. MACHINE REQUIREMENTS

Standard input and output units, ECPL input file, ENDF output file plus two scratch units. If available on/off line plotter. 400 Kbytes of core storage.

14. OTHER PROGRAMMING OR OPERATING INFORMATION OR RESTRICTIONS

Since
no assumptions or restrictions are made, the program in principle can translate all data in ENDL transmittal format (e.g. ACTL), but it has only be checked with ECPL.
