| Research Abstract |
Nuclear level density is one of the important ingredients for performing nuclear reaction simulation. We invented a new code calculating nuclear level density which correctly takes into account pairing interaction, which has been neglected or approximated in preceding studies. As a consequence, it became possible to predict neutron reaction cross section in more reliable accuracy through the nuclear reaction simulation. We also established new method that introduces Lambda particle into a nucleus as an impurity to investigate nuclear fission. Using this method, we clarified the mechanism of formation of fission barrier.
