3. DESCRIPTION OF PROGRAM OR FUNCTION

Pre-equilibrium (exciton) model calculations of nucleon and/or gamma spectra and cross sections. Multiple emission included, all calculations performed with the master equation approach. Incident: up to alphas, but author has also a heavy ion version.

[ top ]

4. METHOD OF SOLUTION

Master equation approach to the exciton model of pre-equilibrium decay without spin dependence, Chatterjee and Gupta algorithm, gamma emission in accord with Akkermans and Gruppelaar.

[ top ]

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM: Up to 100 energy steps, up to 4 successive nucleons.

6. TYPICAL RUNNING TIME

1 min 40 sec compilation, 7 min test run calculation (PC/AT).

IAEA1185/01

NEA-DB compiled the program and executed the test case included in this package on an IBM PC/AT personal computer. Execution time was 8m50s.

7. UNUSUAL FEATURES OF THE PROGRAM

Fully pre-equilibrium approach based on the master equations for the exciton model with subsequent emissions and couplings among various nuclei and energies. Pre-equilibrium gamma emission. Also compound nucleus (=equilibrium) emission treated within the pre-equilibrium formalism

8. RELATED AND AUXILIARY PROGRAMS

PEQAG2 is an updated version of PEQAG (E. Betak, Report IAEA INDC(CSR)-016/LJ (Vienna 1989). Both PEQAG2 originated from mainframe version named PEQGM (E.Betak, J. Dobes, Report IP EPRC SAS 43/1983 (Bratislava 1983)).

11. MACHINE REQUIREMENTS

The program EXE-form requires 423 Kb, a keyboard (display, console) to specify the input and output files, and sufficient space to create the output file (on a disc). The test run output file needs 58 Kb.

IAEA1185/01

IBM PC/AT with math co-processor INTEL 80287. The .EXE file requires 427 kbytes of main storage.

12. PROGRAMMING LANGUAGE(S) USED

Package ID	Computer language
IAEA1185/01	FORTRAN-77

[ top ]

13. OPERATING SYSTEM UNDER WHICH PROGRAM IS EXECUTED: DOS including standard FORTRAN compiler.

IAEA1185/01

MS-DOS 3.20. Compilers: Micrsoft FORTRAN V5.00; Ryan- McFarland RM/FORTRAN V2.42.

14. OTHER PROGRAMMING OR OPERATING INFORMATION OR RESTRICTIONS

For
user with larger memory and operating system allowing to handle it fully, one can advise to re-dimension the arrays as to allow for more energy steps and/or more different exciton states considered.

IAEA1185/01

Only the MS FORTRAN V5.00 compiler produced reasonable results at all outgoing energies. Programs compiled with other compilers should therefore carefully be checked.
