INTER-PRO-UMCS

Description of the project

The project deals with one of the most important pheomenon in nuclear physics: the fission of atomic nuclei. The common investigation of the Polish and Chinese teams consist of the following main tasks:

1. Evaluation within the macroscopic-microscopic model of potential-energy surfaces for cold as well as hot and rotating nuclei in a large deformation parameter range starting with oblate shapes and ending with scission conforgurations.
2. The potential energy calculations from the qst point will be repeated for dsome selected nuclei using the selfconsitent mean-field approach together with Gogny effective interaction.
3. Solving of the Langevin equation for the dissipative fission dynamics coupled with the Master equations for particle evaporation for several heavy (Z<76), excited and rotating nuclei potentially accessible in the experiment.
4. An appropriate 3D collective Hamiltonians describing low energy nuclear fission will be constructed and their eigenstates evaluated within the WKB and Born-Oppenheimer approximation will be used to obtain the fission-fragment mass and total kinectic-energy (TKE) yields.
