GEF 2014/1.2
General description of fission observables. Released January 25, 2014.
(Modified description of multi-chance fission.
Prompt-neutron spectrum slightly shifted in energy after correction of binning problem.)
(Some technical corrections applied on February 1, 2014, without changing the physics of the model.)

Stand-alone version (Monte-Carlo method)
The
stand-alone version of the GEF code is written in FreeBASIC (a). The
FreeBASIC compiler produces binary code from the same source on Windows
(b) and on Linux. The executable uses the C library. For the Windows
version, a GUI is provided, written in JustBasic (c). The Windows
version runs also on Linux with Wine (d).
Quick start on Windows:
- Download the binaries (that includes some additional files).
- Start GEF.bat in a command window.
- Fill in the input mask of the graphical user interface and start the calculation.
- Output is written to file \out\... .dat.
Quick start on Linux:
- Download the binaries.
- Make sure that the binary file GEF is executable.
- Enter ./GEF in a command window.
- Answer the input dialogue.
- Output is written to file /out/... .dat.

You
may consider using the Windows version of GEF on Linux with Wine in
order to profit from the more comfortable input handling offered by the
graphical user interface. This option may also solve problems of missing libraries under Linux.
Subroutine (Folding method)
The subroutine aims for being used
in combination with other nuclear-reaction codes. For a given
fissioning nucleus with excitation energy E* and angular momentum I it calculates a number of fission observables with the GEF model.
