| Research Abstract |
Fusion-evaporation reaction using actinide target nuclei is extensively used to produce super-heavy nuclei (SHN). The fusion reaction itself, however, has not been fully understood, which makes it difficult to predict the production cross sections of SHN. We proposed a method to determine the fusion probability by measuring heavy-ion induced fission. Effect of nuclear deformation on fusion was investigated, and it was shown that SHN can be produced at sub-barrier energies.
