Effects of neck and nuclear orientations on the mass drift in heavy ion collisions
Shota Amano, Yoshihiro Aritomo, Masahisa Ohta
We clarified that the fusion hindrance in heavy ion collisions is caused by the expansion of the neck bridge at the early stage of collision [Phys. Rev. C 108, 014612 (2023)]; howe…
The origin of correlation between mass and angle in quasi-fission
S. Amano, Y. Aritomo, S. Ishizaki +2
Mass-angle distribution (MAD) measurement of heavy and superheavy element fragmentation reactions is one of the powerful tools for investigating the mechanism of fission and fusion…
Modes of massive nucleon transfer appearing in quasifission processes for collisions of superheavy nuclei
S. Amano, Y. Aritomo, M. Ohta
It is challenging to distinguish between fusion-fission and quasifission experimentally. To determine the characteristics of quasifission processes associated with dominant phenome…
Dynamical mechanism of fusion hindrance in heavy ion collisions
S. Amano, Y. Aritomo, M. Ohta
In the fusion process, the investigation of the reaction dynamics in the time evolution of the nuclear configuration is necessary. The neck parameter which is one of the parame…
Nuclear viscosity estimated by dynamics of neck formation in the early stage of nuclear collision
S. Amano, Y. Aritomo, M. Ohta
The very early stage of the coalescence of two nuclei is studied and used to estimate the nuclear viscosity. The time evolution of the neck region has been simulated by the unified…
Fusion cross section and total kinetic energy of fission fragments by the dynamical dissipative surface-friction model
S. Amano, Y. Aritomo, M. Ohta
The capture cross section, the fusion cross section, and the quasi-fission yield producing symmetric fragments () in the Ca+U reaction are analyzed b…
