RSIC COMPUTER CODE PSR-003

1. NAME AND TITLE

ELIESE: Analyses of Elastic and Inelastic Scattering Cross Sections.

The code is packaged in the NEA Computer Program library as ELIESE 1, Abstract 123.

2. CONTRIBUTOR

Japanese Nuclear Data Committee, Japan Atomic Energy Research Institute, through the NEA Computer Programme Library, Ispra (Varese), Italy.

3. CODING LANGUAGE AND COMPUTER

Fortran IV; IBM 370.

4. NATURE OF PROBLEM SOLVED

ELIESE is designed to calculate any kind of cross sections for elastic and inelastic scatterings of neutrons, protons, and alpha particles.

5. METHOD OF SOLUTION

The optical model is used for elastic scattering and the Hauser-Feshbach method of treating the compound nuclear process is used for nonelastic scattering.

6. RESTRICTIONS OR LIMITATIONS

The maximum number of energy levels is 30.

There is some discrepancy between results obtained on the FACOM 230/60, a 36-bit word machine, and the IBM 370/165, a 32-bit machine. This is less than 0.1 percent for the more important physical values and up to 2 percent for the less important ones.

7. TYPICAL RUNNING TIME

No study has been made by RSIC of typical running times for ELIESE.

8. COMPUTER HARDWARE REQUIREMENTS

ELIESE is operable on the IBM 370 computer.

9. COMPUTER SOFTWARE REQUIREMENTS

A Fortran IV compiler is required.
