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.
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.
