| Outline of Final Research Achievements |
We investigate the microscopic mechanism for the steep falloffs of the fusion cross sections, compared to the standard coupled-channel calculations, observed at extremely low incident energies. In our previous study, we indicated that the steep falloffs of the fusion cross sections, called the fusion hindrance, is response for the smooth transition from the sudden to the adiabatic processes. To achieve it, we phenomenologically introduced the damping factor in the standard coupled-channel calculations. Thus, to investigate the microscopic origin of this damping factor, we extend the random-phase approximation method to the two-body systems and calculate quantum vibrations of the individual colliding nuclei, when two nuclei approach each other.
