| Outline of Final Research Achievements |
Nuclear reactions are fuel of stars and microscopic processes to produce heavy elements in stars and stellar explosions. Nuclear fusion and fission processes are particularly important reaction mechanisms. They are collective motions, involving many nucleons, of quantum nature with strong anharmonicity, which is a challenging subject in theoretical physics. These reactions are also closely related to low-energy collective excitations in nuclei. Thus, they are of great interest as a problem of nuclear structure. Conventional approaches to these problems assume its reaction path and adjusting the potential. In the present research, we remove all these assumptions and start from nucleonic degrees of freedom. We have achieved to derive the collective Hamiltonian for a fully non-empirical description of the nuclear reactions.
