GEF 2025/1.1
General description of fission observables,
released on April 6, 2025.

Short characterisation of GEF 2025/1.1:

Compared to GEF 2024/1.1, the following modification have been applied:
- The description of the height of the third fission barrier has been modified for a better reproduction of spontaneous fission of Pu isotoes.
- The critical pairing energy has been set to 9.5 MeV for a better description of the properties of prompt neutrons.

The full GEF code, inclluding the delayed processes after beta decay is available here.
Special options can be produced by re-compiling the code after chosing the appropriate options in the source code.
