Description
There is a large variety of models to describe the fission process, from phenomenological to microscopical, with eventually a time dependence. The SPY model takes advantage of the microscopic description of the static properties of the nucleus (energy, nucleon distribution, and state density), based on the HFB method, and the simplicity of the statistical description of the fission process at the scission point, which allows one to perform systematic calculations from light fissionable nuclei like mercury isotopes up to superheavy nuclei produced during r-process stellar nucleosynthesis. The impact of fragments' nuclear properties on the fission process can easily be studied. In this work, the SPY model will be presented, and some results, including systematic calculations based on Gogny D1M nucleon-nucleon interaction, will be discussed. In conclusion, some outlooks will be given.
