IAEA1328 ISABEL, EVA, PACE-2.

1. NAME OR DESIGNATION OF PROGRAM:  ISABEL, EVA, PACE-2.

3. DESCRIPTION OF PROGRAM OR FUNCTION

The package consists of three programs, ISABEL INC, EVA, and PACE-2. ISABEL and PACE-2 are part of the LAHET code. - ISABEL is an intra-nucleon cascade program. The output cascades are used as directly as input files to the two evaporation programs EVA and PACE-2.- EVA ignores the effect of the  angular momentum of the excited nuclei on the deexcitation and also  ignores the possibility of gamma emission as long as particle emission is energetically allowed. - PACE-2 takes full account of angular momentum effects including irast levels and gamma emission at all stages of the evaporation chain.

4. METHOD OF SOLUTION:

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

EVA ignores the effect of the angular momentum of the excited nuclei on the deexcitation and also ignores the possibility of gamma emission as long as particle emission is energetically allowed. EVA should therefore only be used for cases where these approximations are acceptable.

6. TYPICAL RUNNING TIME

Running times for PACE-2 are at least an order of magnitude grater than for EVA.

The test cases included in the package where executed at the NEA Data Bank on a PC with Pentium 166MHz processor. The following execution times were required- ISABEL: 1m17s; PACE2: 2m44s; EVA: 10s.

7. UNUSUAL FEATURES OF THE PROGRAM:

8. RELATED AND AUXILIARY PROGRAMS

ISABEL and PACE-2 are part of the widely used LAHET code.

11. MACHINE REQUIREMENTS:

The programs of this package were installed at the NEA Data Bank on a DELL OptiPlex GXi desktop computer with a Pentium 188MHz processor.

13. OPERATING SYSTEM UNDER WHICH PROGRAM IS EXECUTED:

The program has been installed at the NEA Data Bank under DOS 7.0 (Windows NT 4.0 and Windows 95). The source codes have been compiled with the Microsoft PowerFortran 1.0 compiler.

14. OTHER PROGRAMMING OR OPERATING INFORMATION OR RESTRICTIONS

The
source codes were adapted for Microsoft F32 FORTRAN. To use the programs on UNIX machines, one only as to omit the clearly marked 'changes for the PC-version' in the source codes.
