Nuclear fission is the process in which a nucleus splits into two daughter nuclei of roughly equal size. Fission of heavy nuclei can be induced by absorbing a neutron. The resulting daughter nuclei then send out neutrons than can induce fission of another nucleus, and thus creating a chain reaction. This is the process used to generate energy in today’s nuclear reactors. Even though fission was discovered almost 80 years ago it is still not fully understood. In this project we extend on well established models and perform systematic calculations of a large number of nuclei. The calculations can contribute to the interpretation of the experimental results in the identifications of new heavy elements as well as to the general understanding of the fission process.
Fusion is the process where two nuclei collide with each other to form a heavier nucleus. The probability that a new element will actually be produced in fusion reactions is very low. Calculations for different reactions and energies are therefore very important
for planning of these kinds of experiments.
